LinuxQuestions.org - Possible race condition between HID-USB and i8042

We recently replaced PS/2 mice with USB optical mice on our networks computers. Only a few sites are having issues, but those who do, continue to see panics on boot with the following backtrace attached.

It looks like there may be a race condition between the hid-usb driver and the i8042 driver at some point during the boot up. This is on RHEL4u5 kernel (2.6.9-55EL.smp). Google wasn't extremely helpful ... i8042.nomux=1 was given as apossibility to pass to the kernel on boot up.

Any ideas would be appreciated. The problem is reproducable about 5 out of 10 reboots, and occurs on RHEL4u2 as well. The site hasn't had time to troubleshoot with me but figured maybe someone has had similar issues.
