Description Thomas Zehetbauer 2004-09-01 01:35:34 UTC 
I am repeatedly seeing hald, [scsi_eh_1], and [usb-storage] lockup in
uninterruptable sleep (D) state while the activity light of my 6in1 card reader
flashes nervously.

Comment 1 Alan Stern 2004-09-01 07:42:23 UTC 
This isn't necessarily an SMP race.  It looks more like a hardware problem with
the USB host controller or a problem with interrupt delivery.  A USB request was
cancelled, and both usb-storage and scsi_eh are waiting for the host controller
driver to acknowledge that the request has been unsuccessfully completed. 
Presumably the HCD in turn is waiting for an interrupt from the controller,
which never arrives.
Comment 2 Matthew Dharm 2004-10-07 09:29:38 UTC 
Is this reproducable in non-SMP mode?
Comment 3 Matthew Dharm 2004-11-11 00:00:51 UTC 
More than 30 days past with no response.  Closing.
