Please try recent 2.6.16-rcX kernels as there have been a number of
patches submitted since 2.6.15 which (attempt to) address most of
these holes -- I'm still trying to get additional details on Maxim's.
387f96b4d9391bf3ce6928fb9cd90c9c7df37291 [PATCH] qla2xxx: Close window on race between rport removal and fcport transition.
77427f514f88143bfef41ba8c1e624bc45f42297 [SCSI] qla2xxx: Drop legacy 'bypass lun scan for tape device' code.
052c40c83b4ca37be226112049b60097cb9961e1 [SCSI] qla2xxx: Correct issue where the rport's upcall was not being made after relogin.
d97994dc1fddcbb8212b745d9c9c9ce96262155c [SCSI] qla2xxx: Correct synchronization issues during rport addition/deletion.
79f89a4296ff22f09baf538d4ff2a6d0c3097a73 [SCSI] qla2xxx: Disable port-type RSCN handling via driver state-machine.
