Subject: Oops with microcode update driver on 2.2.19pre3

I am getting the following oops while trying to update the microcode of a
PII@266mhz using the microcode update driver.  Below is the output of
ksymoops. This was built using egcs-1.1.2.  

Also in case it matters I've applied the ide-2.2.18 patch so I can use my
Promise ATA66 controller and the latest reiserfs patch..

Regards,

Aaron
