Hi. There seem to be the grave bug in that kernel. When either process is trying to access the cdrom, it gets stuck in the kernel forever. Even "eject" locks up. This started to happen somewhere around -mm4 I think. Specifying "pci=routeirq" makes the kernel to deadlock at boot, right after detecting the cdrom. Sometimes there are the "ide1: lost interrupt" messages on console. Attached are the different bits of info I found usefull for that report. It includes the Alt-PrtSc-t trace and the random info about my cdrom. Any suggestions on getting this fixed? This one is really severe I suppose.
