(Std. kernel but customized to my hardware, DDB turned on)
>Description:
Using a PS/2 mouse with std. PC kbd and psm0 enabled causes the
following kernel trap after a while (with DDB turned on):
instruction pointer = 0x8:0xf01887cb
stack pointer = 0x10:0xf01a1f3c
frame pointer = 0x10:0xf01a1f40
code segment = base 0x0, limit 0xfffff, type 0x1b
= DPL 0, pres 1, def32 1, gran 1
processor eflags = interrupt enabled, IOPL = 0
current process = Idle
interrupt mask = tty
kernel: type 29 trap, code=0
Stopped at _read_kbd_data_no_wait+0x37: andl $0xff,%eax
>How-To-Repeat:
Hook up a mouse with PS/2 connector, turn on moused, and
move the mouse around for a while. Happens in X too.
>Fix:
Not known.
