Hm, while running with the first patch (the one trying to build
an interrupt router table for my chipset) my system locked solid
for a few seconds while I was copying the kernel-source to another
place and moved from one virtual screen to another in X.
It happened just once, but I don't remember the last time I had
this kind of latency. At the same time I noticed this in my
kernel logs:
localhost kernel: cdrom: open failed.
I haven't done anything with my cdrom since the last reboot.
\x1a\x1a

localhost modprobe: modprobe: Can't locate module block-major-8
localhost last message repeated 15 times
I only have hd[a-c]
(timestamps removed to prevent irritating wrapping,
they were all in the same minute)
My dmesg is attached, just in case.
