SubjectRe: qstor driver -> irq 193: nobody cared
From
Date
Sorry for the long delay, I've been called on too
many issues at work this week.

Anyway, the patch basically made the drives not usable.
Here is the log from the boot process:

md3 is software RAID 5 composed of sda through sdd, which are
the disks attached to the qstor.

I went back to the old kernel to be able to use this
array.

Any ideas?


Thanks,

Alberto
