In short the whole system gets noticeably choppy (even with preempt) - especially when looking at webpages with lots of graphics. I'll leave to your imagination what these pages are ;) Since it seems IRQ related I tried all the standard things. Disabling ACPI, enabling ACPI (both in kernel and BIOS), PnP options in the BIOS, kernel boot options (pci=routeirq among others), removing cards and turning off anything that used an IRQ in the BIOS. Eventually I was left with nothing but sound and graphics and IDE. Still, the problem remained. Trying another sound card was fruitless as well. Attached is the dmesg output (with alsa xrun_debug at the bottom, which pointed me to this being IRQ related) from that basic configuration. Google turned up some results that showed similar problems with early implementations of ACPI and / or early 2.6.x kernels. Why I seem to be the only one with these problems and such a recent version of the kernel I don't know. I'm certainly willing to what I can in order to get this problem resolved. Thank you.
