The deadlock is quite reproducible. Ever since I upgraded to 2.2.16,
I had my machine deadlock four or five times. This always happens
after a few hours uptime, and it always happens right after I touched
the mouse. Unfortunately, at that stage the machine is completely
unresponsive and I cannot do any more debugging. That's why I thought
that it might have to do with PS/2 changes that have just been made.
But maybe it is an interrupt problem? As far as I can tell, there
shouldn't be anything unusual. The first thing that I checked was,
whether IRQ 12 was shared; but it seems to be handling just the mouse.
So that appears to be OK. I am a little at a loss what to do now;
any suggestions as to how to trace down the bug would be very much
appreciated.
