Subject: Keyboard broken in 2.6.13.2

I have a system with a super-micro P8SCI motherboard.

The default FC2 kernel (2.6.10-1.771_FC2smp) works fine, but
when I try to boot a 2.6.13.2 kernel, I see this error:

i8042.c: Can't read CTR while initializing i8042

If I hit the keyboard early in the boot, the system will just reboot.

If I wait a bit, then it will boot to a prompt, but no keyboard input
is accepted.

Thanks,
Ben

Does booting with "usb-handoff" boot option help any?

Not sure, but acpi=no works.

Thanks,

Fedora Core has a patch (which was rejected upstream) which
automatically fixes up problems with some BIOS USB emulation. On the
base kernel you need to specify "usb-handoff" on the command line at
boot. Another approach is to turn USB keyboard off in the BIOS.
