Hi Andrew! Unfortunately I see that scan-work patch is not included in 2.6.16 and the usual lock appears: #001: [ffff8100708a8080] {scsi_host_alloc} .. held by: scsi_wq_4: 3912 [ffff810071edf870, 110] ... acquired at: scsi_scan_target+0x51/0x87 [scsi_mod]
Applying the patch you sent solves the problem, i.e. disks appear again after 22 sec timeout (why?).
Thanks,
Maxim.
