this look like firmware hang. This happen just after module load, that's
good news, because it allow to log relative small amount debug messages
to see what possibly driver do wrong to crash firmware.

Note, that the effects of - usually but not always - frozen system while
the errors are printed (sometimes keyboard input seems still be possible
during that) ... happen over and over again... say about every  10 minutes
or so.
Not just the first time the modules is loaded.
Is the firmware loaded over and over again?

I think is not, but even if is, kernel should not crash. Can you grab
crash logs using photo camera, serial cable or netconsole, to allow to 
see where exactly crash happen and fix it.

Please configure syslog to log kernel debug messages.

Will mail it later.

Firmware hang seems to happen when REPLY_LEDS_CMD command is send.
No idea if attached patch could help or not, but is worth to try it.
It prevent to send LED command asynchronously, when possibly some
other commands are pending in firmware.

If it does not help, please provide the same way captured debug
messages from 2.6.38 kernel, where drivers works. I'll compare
it with broken driver logs to figure out what broken driver
do differently.

Sorry, forgot attch the patch, do it now.
