Red Hat Bugzilla – Bug 214538
USB HID devices not recognised with SMP kernel
Last modified: 2007-11-16 20:14:54 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
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.
