NetBSD stallion ...

>Description:
After replacement of the keyboard cable NetBSD's pckbd driver produces a lot of output like

May  5 21:35:04 stallion /netbsd: pms_enable: command error 35
May  5 21:35:04 stallion /netbsd: pms_enable: command error 35
May  5 21:35:06 stallion /netbsd: pckbport: command timeout
May  5 21:35:06 stallion /netbsd: pckbport: command timeout
May  5 21:35:06 stallion /netbsd: pms_disable: command error
May  5 21:35:06 stallion /netbsd: pms_disable: command error
May  5 21:35:10 stallion /netbsd: pckbport: command timeout
May  5 21:35:10 stallion /netbsd: pckbport: command timeout

whilst rejecting any (terminal) input (VT switching is possible trough).

The problem seems to be pecular to NetBSD, ((Debian) GNU/Linux for example doesn't even complains about it.
Indeed, NetBSD is extremely correct, but rejecting a working keyboard because of a minor failure is too much
IMHO, I hope that developers would be kind enough to change the current behaviour :-)

(If it's relevant, the keyboard is BTC 9110 with PS/2 interface)


>How-To-Repeat:
You may venture to manually replace an expendable keyboard's cable :-)

Responsible-Changed-Why:
Driver bug, hence "kernel" category.

note btw that PS/2 keyboard/mouse ports are not meant to be hot-swappable
and you can in theory fry your motherboard by trying it...
