Graphics HW is ATI RV250Lf, no 3D.

It *is* related to ACPI - starting the kernel with acpi=off removes the problem - and of course some desirable features :-( This was not required with 9.2, and I did *days* of live recording with that setup without a single incident, so I don't think it's the BIOS. I killed everything related to acpi - no effect. There seems to be a new process [kacpid] that I can't remember having seen before. It can't be killed, and I can only assume the problem is somewhere inside that one. I tried all sorts of BIOS interrupt assignments, nothing helped. So maybe the only solution is a patched kernel... Now, probably because I'm using -n 3 on USB, all of this happens without any effect on the audio, but qjackctl doesn't like the shower of messages, and also ardour's cpu load goes way up for some seconds after the timeout events, so it's not a healthy situation. -- FA ------------------------------------------------------- This SF.net email is sponsored by: Splunk Inc.
