Distribution is SUSE 9.0 Professional. Kernel is kernel-default-26-2.6.1-4 from ftp.suse.com/pub/people/kraxel which is basically 2.6.2-rc1. I assume the lockup happens because interrupts are not disabled for the device. Debug traces are not available since SysRq-T and SysRq-P do not work. The nmi watchdog does not work on my hardware. The only SysRq keys that work are "O" and "B" to switch the machine off/reboot it. Right now, I can disable the rmmod, but that's not a solution for long. Please take a look at the module unloading function and fix it if possible.
