keyboard stopped working after de9ce703c6b807b1dfef5942df4f2fadd0fdb67a

[Christoph Pfister]

Hi,

After a kernel update I recognised that my keyboard sometimes didn't work 
after booting up. I found out that the issue appeared quite reliably after a 
cold reboot and not pressing any key (for example not selecting stuff at the 
bootloader) till the machine fully booted up.
Because git head (4eb6bf6bfb580afaf1e1a1d30cba17a078530cf4) didn't solve the 
problem I did a bisect and your commit was found to be the culprit (the 
second last build succeeded 5 of 5 times during my tests and the last build 
failed 2 of 3 times).

Can anybody please shade light on this?

Thanks,

Christoph

Forgot to mention dmesg: "input: AT Translated Set 2 keyboard 
as /class/input/input0" is shown in both (working / failing) cases (no 
additional / related lines nearby).

Could you please boot with "i8042.debug log_buf_len=131072" and send
me full dmesg?

Thanks!

Yep, attached (cold reboot, not pressing any keys, 2.6.21).

Ok, I see. You don't use PS/2 mouse and so BIOS told us that mouse is
absent and reassigned IRQ12 to EHCI controller. However we do not
listen to BIOS on i386 (for historucal reasons) and process with
registering AUX port... Now IRQ12 is shared between AUX port and EHCI
and the keyboard controller is unhappy wehereas before (with polling
timer) it would release IRQ12 and close port...

Does your keyboard start working if you boot with i8042.noaux?

Yes, that makes it working and I can live with it for the moment. If you 
intend to change something and need somebody to test it just drop me some 
lines =)

Thanks!

Here I should add that IRQ sharing between ISA/LPC where i8042 lives and
PCI where EHCI lives doesn't work - only one of the sides will ever be
able to trigger interrupts, depending on the bridge config.
