First thing that pops up in my mind is CPU frequency scaling (disabling the Ondemand service),
That might be. Again I might have falsely assumed that that goes for my laptop (2Ghz dual core) applies to his. Still I never had problems like the ones he has with frequency scaling. Seems to matter at high loads but with nothing using jack it has never been a problem to me, but it's worth a try!
but apparently it's an old laptop so maybe it doesn't apply.
Maybe, I'm not sure exactly how old, I guess a cat /proc/cpuinfo would be useful...
And Firewire can be very picky when it's an onboard Firewire chipset. If so it could share an IRQ and then you most probably have to use rtirq to get it running in a stable way.
Ah, I didn't think about that. It could be his firewire chipset is one of those buggy/crappy ones people curse over here from time to time. Again I never met one of those, should have thought about that.
I used to be really into tuning my IRQ's but now it doesn't really seem to matter anymore. Maybe that'll make a difference on his hardware.
Thanks for all the ideas so far! Seems to be lot's of stuff I forgot about...
