Ok, since 2.6.20, there been a patch added to qla2xxx which drops the
spin_unlock_irq() call while attempting to ramp-up the queue-depth:

[SCSI] qla2xxx: correct locking while call starget_for_each_device()
Removed spin_unlock_irq()/spin_lock_irq() pairs surrounding
starget_for_each_device() calls.
As Matthew W. pointed out, starget_for_each_device() can be called
under
a spinlock being held.
The change has been tested and verified on qla2xxx.ko module.
Thanks Matthew W. and Hisashi H. for help.

Could you try the latest 2.6.21-rc which contains the correction?
