And it is always using AHCI enforced via kernel, regardless of BIOS setting. So that is ruled out as source of the issues. The onboard soundchip performance is still not stellar, but it is able to do 2x1024 in an apparently stable manner. What matters, is the Edirol FA-101 on Firewire and there, I can happily record with 3x64 if I really want to. My standard setup of 3x512 periods was idling around (jack and meterbridge running) over the whole day and did not experience a single xrun. I still added the rtc setting to rtirq, which didn't change anything I could perceive. I also swapped the firewire card back into its previous slot. No difference, still fine. I have to conclude that this really is about either a BIOS setting (I didn't do that much ... could disabling the internal audio chip trip things up?!) that got reset when I took out the battery or that indeed, the flaky power train triggered unstable behaviour of the machine; which would confoundedly confuse me as I would expect a more drastic failure mode. Thanks for jumping to help me about this ... I'll keep an eye on this box and report if I find a definite clue. For now, I'll try to just use it, not waste time breaking the setup again. I hope you can understand that;-) Alrighty then, Thomas
