After downloading and compiling the latest version 2.6.12, my
keyboard becomes unresponsive and dead following the boot process.
This doesn't occur all of the time, but only some of the time.
In particular, the follwing boot up message will be seen at
sporadic places among the other text output:

input: AT Translated Set 2 keyboard on isa0060/serio0

When this message does not occur anywhere in the boot messages,
the keyboard is not functional.  When the message does occur, then
the keyboard will respond, but sometimes with an erratic key
repeat rate.  After rebooting several times I can usually get
the system up and running smoothly, but with this current kernel
2.6.12, there is no guarantee that it will boot properly at any
given time.
...

My system is an ASUS P4B533 motherboard with a Pentium 3.6 Ghz
Hyperthreaded processor and 1 GHz RAM.  The kernel is the stock
linux kernel (compiled with gcc-2.95.3) and the rest of my software
is self-compiled (i.e. no distribution).

If I disable ACPI, either by compiling a new 2.6.12 kernel or
through boot up parameters, the keyboard will respond normally
without any problems, but the kernel will not recognize my
hyperthreaded processor.  Only one CPU will be initialized and
active.

Thus, I can enjoy a problem-free 2.6.12 kernel if I choose to sacrifice ACPI and hyperthreading.

I am having the same problem with my Shuttle FT61 motherboard, although I have not tried to disable ACPI... Until now I thought I just had a faulty keyboard, as my method to fix this was to unplug the keyboard and plug it back in after bootup. When this happens, I see this in dmesg as the last line:

input: AT Translated Set 2 keyboard on isa0060/serio0

I am also having problems with my AUX mouse, as seen in message

Subject: 2.6.12-rc5-mm1 breaks serio: i8042 AUX port

Frank, are you having problems with your ps/2 mouse port as well?

I haven't spent enough time experimenting with this, as I thought it might have had something to to with my hardware / KVM switch. Seeing Frank's message is the reason why I've decided to chime back in on this.

As a clarification, I have been having these keyboard problems intermittently, regardless of whether I'm using -mm or mainline kernel. I was NOT having this problem in 2.6.11 I wasn't having the psaux mouse problems in 2.6.11 either .... I unplugged my psaux mouse from that machine before 2.6.12-mainline was released, so I don't know if those symptoms are still present. (using USB mouse now instead). I am currently in my office, so I can't test this right now, and I will be away for this weekend. I'll be able to make these tests again come Sunday night/Monday. ...and I will try it this time WITHOUT the kvm switch.

I tested the above scenarios with 2.6.12-mm2 and everything is working normally again. ...still having input problems with older -mm kernels, but if -mm2 is working then I must assume that the problem, (at least MY problem) has already been fixed.

Thank you!
