hello, in my own special case i suspect some general kernel incopatibilty problem with the mainboard (chipset via VT82C686B) - i'll dig deeper into it as soon as i have more time (but then i won't need that pd patch anymore, that's life)
hard-coded hacking the buffersize to 1024 helps just to get to 4 track output - any more track blockes again. (and i had to stop cron and any other harddisc consuming task) -
again thank you all for your suggestions - you gave me a lot of insights.

My understanding is that the RME has the number of fragments set at 2 as a hardware property. I don't see why the drivers couldn't do more buffering, however.

Hi all,
I don't understand why 64 sample buffers should be a problem for RME since you should be able to use many buffers ("fragments") to set the latency to a reasonable value. But perhaps I'm mising something...

this should definitely rock ! note, that i do not remember having problems with a rme-9652 and kernel-2.4.3 (or something), although i had to compile the kernel myself then. i am sure, that i could play-bac 2 files at least.
which soundfile-player do you use ? under linux i definitely suggest using miller's "readsf" instead of zexy's "sfplay~" !! could this be the problem ?
I don't think so. I'm not sure if the pd-0.34 has the same thing, but the buffersize for the RME is changed to use 64 samples (the smallest buffer you can get for the rme), no matter what buffersize you request.
Linux without the low latency patches isn't suited for this short buffers when doing harddisk I/O.
Even with lowlatency you are living on the edge with this setting.
The only way I found to change this was editting s_linux.c
