Description Ben Stringer 2006-11-07 21:31:26 EST
Description of problem:
USB keyboard and mouse not recognised when booting with SMP kernels. Hardware 
is a Dell Optiplex 280, with hyperthreading-capable Celeron processor.

Version-Release number of selected component (if applicable):
kernel-smp-2.6.9-22.EL and kernel-smp-2.6.9-42.0.3.EL

How reproducible:
This is occurring consistently. Booting with the equivalent UP kernel versions 
works as expected.

Steps to Reproduce:
1. Boot with SMP kernel
2. After GRUB screen, keyboard and mouse are unresponsive.
3. Boot with UP kernel - keyboard and mouse work as expected.
Actual results:
SMP kernels do not recognise USB HID devices.

Expected results:
USB HID devices should be recognised and work.

Additional info:

When booting with UP kernel, the following is logged in /var/log/messages:

  kernel: input: USB HID v1.10 Keyboard ...
  kernel: input: USB HID v1.10 Mouse ...

When booting with an SMP kernel, these lines are not logged.

I need at least dmesg for both UP and SMP.
Comment 3 Pete Zaitcev 2007-02-21 19:44:35 EST
Ben, please give me two dmesgs... I need at least something to look at,
because I'm baffled without data.

Also, since this is the 280, attach the output of dmidecode as well.
The 280 is known to have defective firmware which has weirdest problems.
I need to get your A-level and pass it over to Dell for checking.

And finally, make sure to have an I-T ticket. It's necessary for RHEL bugs.
