SubjectRe: keyboard locks in 1.3.9x
Michael B Herf:

: I have a Quickcam (which takes keyboard power) and a Microsoft Natural
: Keyboard -- no problems on the 1.3.7x kernel I've been running.
: However, upgrading to 1.3.9x shows "Keyboard error" in the logs, at
: which point the machine refuses to respond to any keypresses until a
: reboot.

A rare but well-known phenomenon. There is one particular kernel
that gives me this effect. There is no obvious relation to kernel source,
and different people complain about different kernels.
Some hardware matter involving the timing of interrupts, I suppose.

Sending an arbitrary command to the keyboard solves the problem.
