Red Hat Bugzilla – Bug 214537
USB HID devices not recognised with SMP kernel
Last modified: 2012-06-20 09:31:36 EDT
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
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.
SMP kernels do not recognise USB HID devices.
USB HID devices should be recognised and work.
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.
*** Bug 214538 has been marked as a duplicate of this bug. ***
I need at least dmesg for both UP and SMP.
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.
