Hi, We got a customer report where qla2xxx was crashing only if the kernel was booting and ql2xextended_error_logging was set. Loading the module with the log option didn't trigger the crash. After starring for a long time at the crash report I figured the problem might be a race between the timeout handler and done callback. I've come up with these patches here but unfortunatly, our customer is not able to reproduce the problem in the lab anymore (it was caused by a hardware issue which got fixed). So for these patches I don't have any feedback. Maybe they make sense to add the driver even if I don't have prove it really address the mentioned bug hence this is marked as RFC.
