    Patch in this message
    SubjectRe: Re: Re[8]: problems with scsi_transport_fc and qla2xxx
    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?).
