Bug Description
Binary package hint: linux-source-2.6.20
PS2 Keyboard does not work on VIA chipset machine with this kernel: there is no response to any key.
Keyboard works in grub menu and BIOS settings. Some more PS2 keyboards were tried.
It was working with the kernel of dapper (it failed after upgrade).
The kernel option apci=off quick-fixes this problem, then the keyboard works.
dmesg lspci and uname is attached.
This bug report was redirected from 108382 which turned out to be SiS specific while this bug is told to be VIA specific.

I also have this problem with a PS/2 keyboard running on a VIA chipset motherboard.
The keyboard does not work:
* when booting into "Recovery mode" (runlevel 1).
The keyboard does work:
* in the BIOS Setup;
* in GRUB;
* when booting into full graphical mode (runlevel 2);
* after switching from full graphical mode into single user mode (sudo init 1);
* in any mode using Knoppix 5.1.1, openSUSE 10.2, and Fedora 7.
The keyboard previously worked correctly in:
* Ubuntu 6.06;
* Ubuntu 6.10.
The keyboard worked sometimes under previous Ubuntu 7.04 kernel revisions if the Num Lock key was pressed immediately after the boot process switched off the Num Lock light. Changing the Num Lock setting in the BIOS has no effect on the problem.
For reference, my specific keyboard is a Unicomp Customizer (formerly Lexmark, formerly IBM), and can be found at http:// www.pckeyboard. com/ .
Other helpful output is attached.
