Hello, I could not find any working link to actual (>2.4.3) LL-kernels and headers. Does anybody know a working location? Thanks, Michael

Have you tried
http://www.zip.com.au/~akpm/linux/schedlat.html#downloads
or
http://www.linuxdj.com/audio/lad/resourceslatency.php3 (There are a few links on this page including the first one I mention)
I have no idea which to use, though.

Hi,
Just wanted to follow up this little thread of a couple of months ago (see marco's message below)
Marco (or anyone) - d'you know of any progress on this issue of laptop BIOS?
Anyone bought a laptop recently & running PD smoothly under Linux?
Looking to buy...
Nick
Hi,
I own a laptop which runs Linux and PD runs very smoothly on it.
The model is an Acer Laptop 528 TXV (PIII, 850 MHz) and it worked right out of the box (with LAN builtin, PCMCIA, DVD, USB, sound bidirectional). Also APM seems to work (without the suspend to disk hibernation mode). Acer kinda support Linux (at least they claim to be supportive) although there is no Laptop with preinstalled linux available.
If you want to learn more about Linux on Laptops, follow the top link if you search for "Linux Laptops" at google. It'll lead you to the Linux Laptop site, which is a Database with howtos for installation on hundreds of laptops provided by their users and sorted by brand.
I have the impression that right now it seems to be hard to find a laptop, which doesn't run linux although there might be minor problems with exotic parts sometimes. Generally speaking: If linux is supported and the soundcard works with ALSA you're fine concerning pd.
Yours, Orm
P.S.:
The whole PnP issue is a little unclear to me since the interrupt configuration of pnp cards under linux is done in the /etc/isapnp.conf file (with very clear explanations how to do that in the isapnp howtos), but I'm no hardware specialist.

Laptops:
Unfortunatelly i must say i would not run to buy a laptop right now...as i did...:-(
Due to a new policy introduced (let say imposed) by Microsoft...all new laptops (and soon i guess also all desktops), do NOT allow anymore access to the BIOS at booting time. This means (briefly) that you are not able for instance to disable PnP and other things and the Linux is not able to assign IRQs to "non vital" devices..i.e. PCMCIA, Sound cards, video (TV) output,firewire...etc.not a very pleasant situation.
All these functions, now, must be controlled and set by and from within the OS. ACPI (that is going to replace APM) will be the way to gain access to the BIOS from the OS but has not reached yet a level of sofistication to make this process easy (if even possible). The only ultra ugly solution right now is to hard link IRQs in the Kernel itsefl....(no comments) Right now even power management is really limited to the minimal. This is a work in progress, and i guess (hope) that will be solved in few months (also because i wiped out W_XP right away from my laptop so i really hope is just a matter of months...).I'm myself working on it (at least as far it concerns my specific laptop).
For record: I got a Toshiba Satellite 5005-S504 which features seem promising:
- DVD- CD-RW - CD
- Sound card with ADC DAC line + headphone + SPDIF optical
- Firewire
- Video (TV) output RCA
- a bouch of USB (neither serial nor parallel)
-Smart Card
- And another card slot i now forgot what is supposed to be for...
- PCMCIA
- 512MB, 1.1Ghz, 30Gb
A part for CD and an external USB mouse, none of these features are working right now.... Hopefully very soon, since the card is supported by alsa, firwire should be and video (tv) out should be as well..... So after this legacy free problem will be solved should be a great machine. (BTW: 2000USD....:-( now you can find it cheapper...already)
What i found good for now (in this bad situation) is that even if Toshiba does not support officially Linux, they have a very active and helpfull linux deprtament (i dont know if "department" is the right definition) in Europe and Japan, and they really help and they do their best to solve problems (like this one). (they have mailing list and they are very responinve and quick) ..and by consequence also the Linux Toshiba community ( i mean toshiba owners) is very alive and efficient... After this experience i had (this is my fist laptop), i would reccomend to put this as FIRST priority when you think about getting a laptop. Also, even if you will find a bit more expensive i would consider to buy from a reseller that ships computer already with Linux...if you dont want to spend about a month (with no problems such as mine raising on the way) to tune it up....
Sorry for this long and almost off topic message, but i think it is also important to share these issues amongst us,because many of us, like me, they have the dream of going to a concert with thier laptop, their PCMCIA or USB professional sound card, and give the concert....with battery only, in order to avoid the "Guenter-effect"...:-))
ciao, marco
I can/t really say how many companies are already following the legacy free standard. If you can find a computer without this "features" (and more important a company who will tell you that) i would buy it.
Even Linus Torvald is working on this BIOS issue. for instance -on my laptop for sure dont know ,again, how many of the new models have already this- APM is out of buisiness, it will be replaced by ACPI. ACPI for Linux (even if Intel itself is releasing the linux port) is still far from being a serious working tool. You could say what APM and ACPI has to do with IRQs? In legacy free computer you must be able to assign IRQ from the OS itself. No way to disable PnP in the BIOS. None of the traditional known ways to set up IRQs work...
I must say that beside the possibility of working with the internal sound card and speaker for testing porpuses, we dont really want to work with it professionally, so i guess PCMCIA cards should work (once driver exists...), then the problem it is solved as wellas USB cards.
Of course all recent models tend to avoid "useless" outputs like: parallel port serial ports. Only USB, USB everywhere...
AH and be carefull about internal modems....
Due to a new born...:-)) in the family i dint have time for much work a part for changing diapers...but as far i know pratically all the features seem to work with the toshiba satellite 5005-Sxxx. DVD, CD writer, USB, PCMCIA, last one with different results. Also video camera output and firewire are reported to work... (not 100% sure about camera output and firewire)
The nice thing about the internal sound card would be the optical output (supported by alsa...) but...untill the IRQ problem is solved there is no way. I got the CD-Rom (audio) working by hadcoding the irq in the kernel itself...and wav sound would play for a fraction of sound then it dies, interrupts problems.
If i had to buy a linux laptop -right now- i would buy with a company that support linux officially.

Anyone bought a laptop recently & running PD smoothly under Linux?
Running pd 0.34-3 rpm for RH 7.2 on Dell Inspiron 2500. After some grief with building an X server which would work with the intel 810 chipset, got kernel patches (botha) and started up. This particular chipset is diabolical with sound also; finally had to buy OSS license for it. I hear other Dell laptop models (later ones) have stopped using it, so maybe more luck there. In all, after the initial hurdle, it runs great; it even likes usb midi...now I just have to get rid of Dead Rat and try demudi...
btw, has anyone put up any comments/suggestions on pd/demudi after Havana?

...not much work has been done after habana. Few upgrades. The system is working, i'm running it on two machines.
Now the projects is in a "sleeping" stage. Guenter is very busy with his new job and i'm very busy too with my new baby.
In few weeks i could go back to demudi and what is really needed now is to find mantainers for the packages included in Demudi Alpha plus new mantainrs for new applications.
Also in spring will start a new european funded project from which DeMuDi should also benefit. So the project is still alive it just needs a bit of reorganization.
So far i'm running demudi on a desktop machine and on a laptop ( a part that i'm having the problems i mentioned in my previous email.)
ciao,
marco

I've missed the thread (and most messages on this list, though, I'm saving them all to read when I can), but seeing this: I'm successfully running PD under RedHat Linux 7.2 on a Dell Latitude CPi D266XT.
