CONFIG_X86_UP_APIC is disabled on my system.
Today I tried some experimenting: after repeatedly switching between vt1 and vt7 for some time I got the lockup. Syslog didn't contain any interesting messages. The counters for keyboard and PS/2 mouse in /proc/interrupts became stuck. One interesting thing I noticed is that PS/2 mouse line disappeared for a short time during console switch. While gpm was running, fuser and lsof indicate that it didn't have /dev/mouse open -- only XFree86 did.
I've waited for about 30 minutes for any keyboard timeouts to appear, but didn't see any. Then I tried chvt 7 with no effect (vt7 was already the active console). Then chvt 1 fixed the lockup. Interrupt counters went alive again. This time fuser and lsof showed that /dev/mouse is opened by gpm only. It looks like both XFree and gpm close /dev/mouse when they're not active, and reopen it then they become active.
I'm now compiling 2.4.9 with some printk()s added in open_aux and release_aux. If I get any interesting results, I'll post them here.
