[Bug 199934] Re: Kernel Panic, in gdth (RAID) driver on reboot

[Stefan Bader]

Ok, just found it:

commit ff83efacf2b77a1fe8942db6613825a4b80ee5e2

    [SCSI] gdth: don't call pci_free_consistent under spinlock
    
    The spinlock is held over too large a region: pscratch is a permanent
    address (it's allocated at boot time and never changes).  All you need
    the smp lock for is mediating the scratch in use flag, so fix this by
    moving the spinlock into the case where we set the pscratch_busy flag
    to false.
