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):
Steps to Reproduce:
1. Boot the SMP kernel.
Actual Results: Keyboard and mouse are unresponsive.
Expected Results: keyboard and mouse should work.
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.
As a work-around, I can confirm that a USB keyboard and mouse work fine.
Also works correctly if booted without the SMP kernel.
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.
hmmm...are you suggesting that -42.EL boots fine with acpi=off?
i've also uploaded kernels to http://people.redhat.com/~jbaron/bz158327/i686/
which might address this issue. could you please test them. thanks.
any chance you can test these kernels? thanks.

No, they panic immediately.
I will test your kernels. Thanks for your help.
ok. chaning to needinfo until i hear back about the test kernels. thanks.
Unfortunately kernel-2.6.9-42.19.EL.keyb.1 does not fix the problem.
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?
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.
It is not working.
