dear Hackers,
i was finally able to trace hard lockup problem with kbdmux(4), ps/2
keyboard and ps/2 mouse under x11.
the problem was traced back to the following code in kbdmux(4)
this is only happening when kbdmux(4), ps/2 keyboard and ps/2 mouse used
together, and, here is why: atkbd_check_char() calls kbdc_data_ready().
the later will return "true" if there are pending data in either kbd or
aux queue.
Hmm, I wonder if this could be the cause of the lockups on my laptop
when using the touchpad. I started using kbdmux a while ago with the
built-in (PS/2) and USB keyboard but never even suspected it when I
traced my occasional hard lockups to using the touchpad.
I'll try the patch tonight and see if it clears up the problem.
Craig
