2.6.10 almost works, but sometimes, the whole input
subsystem just "hungs", ie, both keyboard and mouse
just stops working. Plugging in USB keyboard and
loading usbhid module solves the problem - both
keyboards and the mouse works after that, and I
didn't yet notice the problem repeats after usbhid
and usb keyboard is loaded. I wasn't able to
determine when the problem occurs, for me it seems
it hangs at some "random" point - sometimes after
5 minutes after boot, sometimes after a hour or
so.
Got another such "hung" and tried to debug it somehow.
Did a task dump (echo t > /proc/sysrq-trigger when logged
from network) -- nothing interesting; kseriod trace looks
a bit weird but it is as weird in normal mode too:

Everything on the system is sleeping.
After plugging in USB keyboard and loading uhci-hcd and
usbhid, the keyboard un-freeze, but mouse still didn't
work. So I tried re-loading psmouse module, and
surprizingly, mouse started working again, but now dmesg
says:
input: PS2++ Logitech Wheel Mouse on isa0060/serio1
(normally it's
input: ImPS/2 Generic Wheel Mouse on isa0060/serio1
)
and the mouse is moving very fast now. Previously
I either didn't able to make it work at all after such
freeze, or it worked automatically after loading usbhid.
BTW, it's 2.6.10, I can't made it work with 2.6.11 at all.
