Description Jeff Woods 2005-05-20 15:27:07 UTC
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.7) Gecko/20050416 Red Hat/1.0.3-1.4.1 Firefox/1.0.3

Description of problem:
When booting a Dell Precision 530 (dual processor workstation), I get the error:

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

The boot continues normally, but the (PS/2) keyboard and (PS/2) mouse are unresponsive.

Version-Release number of selected component (if applicable):

How reproducible:

Steps to Reproduce:
1. Boot the SMP kernel.

Actual Results:  Keyboard and mouse are unresponsive.

Expected Results:  keyboard and mouse should work.

Additional info:

This seems to be a duplicate of a number of existing bugs entered against Fedora, but I cannot find a solution to this problem.  I am working with RHWS 4.

Comment 1 Jeff Woods 2005-05-20 19:56:26 UTC
As a work-around, I can confirm that a USB keyboard and mouse work fine.

Comment 2 Jeff Woods 2005-05-20 19:57:34 UTC
Also works correctly if booted without the SMP kernel.

Comment 5 Gerald Teschl 2006-10-16 08:35:19 UTC
We have the same problem on all of our HP workstations. However it happens with
or without the smp kernel.

As a workaround we used to boot with "acpi=off" but the latest kernels
kernel-2.6.9-42.0.2.EL and kernel-2.6.9-42.0.3.EL will panic with this

Another workaround is to type something while the kernel is booting, but
this isn't really an option for user workstations;-)

BTW, this seems a redhat only thing. I testet kunbuntu and knoppix which
both don't have this problem.

Comment 6 Jason Baron 2006-10-18 15:54:41 UTC
hmmm...are you suggesting that -42.EL boots fine with acpi=off?

Comment 7 Jason Baron 2006-10-18 22:16:50 UTC
i've also uploaded kernels to http://people.redhat.com/~jbaron/bz158327/i686/
which might address this issue. could you please test them. thanks.

Comment 8 Jason Baron 2006-10-24 22:13:18 UTC
any chance you can test these kernels? thanks.

> hmmm...are you suggesting that -42.EL boots fine with acpi=off?

No, they panic immediately.

I will test your kernels. Thanks for your help.

Comment 10 Jason Baron 2006-10-26 17:35:42 UTC
ok. chaning to needinfo until i hear back about the test kernels. thanks.

Comment 11 Gerald Teschl 2006-11-02 14:23:10 UTC
Unfortunately kernel-2.6.9-42.19.EL.keyb.1 does not fix the problem.

Comment 12 Jason Baron 2006-12-05 23:23:41 UTC
can you please try passing "i8042.noacpi" on the command line for the
kernel-2.6.9-42.19.EL.keyb.1 and see if that fixes things?


Comment 13 Gerald Teschl 2006-12-08 21:38:16 UTC
I don't have physical access to the boxes right now, but I booted with "i8042.noacpi"
and dmesg still gives me:

i8042: ACPI detection disabled
i8042.c: Can't read CTR while initializing i8042.

So I presume it is not working.

Comment 14 Gerald Teschl 2006-12-14 19:15:50 UTC
It is not working.
