Hi Igor,
I am not able to reproduce the issue any longer with the two patches on top of the mainline linux.
Thank you very much!

Hacks to mask a race between HBA scan job and bridge re-configuration(s) during hotplug.
I don't like it a bit but it something that could be done quickly and solves problems that were reported.
Other options to discuss/possibly more invasive: 1: make sure pci_assign_unassigned_bridge_resources() doesn't reconfigure bridge if it's not necessary. 2. make SCSI_SCAN_ASYNC job wait till hotplug is finished for all slots on the bridge or somehow restart the job if it fails 3. any other ideas?
