Hi Andrew!
Please see the log with debug-patch.
The module is loaded with option qlport_down_retry=1.
Adapter 4 is connected to switch, adapter 5 doesn't have cable attached.
After reconnecting the cable the disks don't reappear and rescan is stuck.
Before applying your patches ghost rport was staying, now it's OK.
Thanks,
Maxim.
