Greetings,
I just bought a USB digital camera, and cannot get it to work
on my desktop system. Symptom is a complete system lockup
about 3 seconds after plugging in the device. This requires
a hard system reset. It is 100% reproducible.
Debugging via the printf() school seems to indicate that the
last gasp is occurring in:
drivers/usb/storage/transport.c : usb_stor_Bulk_reset()
...right aroung the schedule_timeout(HZ*6). It makes it past
the TASK_UNINTERRUPTIBLE, but never past the timeout. Alas,
my SMP skills are 10 years rusty; I have been unable to find
the root cause nor to develop a patch.
Notes:
* I have tried disabling the secondary CPU from BIOS. No effect,
system still locks up.
* I have not tried building & running a non-SMP kernel on this machine.
* IBM Thinkpad 600E with same kernel (sources rsync'ed over, but
different config of course) works perfectly. No lockup, usb-storage
configures the Bulk driver, new device /dev/sda1 appears, camera
mounts just perfectly. FWIW Thinkpad does not have SCSI drives,
has only one CPU, and has no ReiserFS partitions.
* I tried adding an entry to unusual_devs.h for the camera,
specifying US_PR_EUSB_SDDR09. With this, the system never hung
(although, unsurprisingly, mount failed later on). But the new
drive did appear in /proc/scsi/scsi and /proc/scsi/usb-*, as
well as /proc/bus/usb/devices. This is consistent with the
problem being associated with set_current_state(), schedule...()
* Camera is Olympus D-150, aka C-1 (no, I didn't know about
the @#$% 'USBU' bug before buying it). Lockup occurs without
the US_BULK_CS_SIGN kludge^Wpatch -- am 80% sure I also tried
with the USBU kludge, but not 100% sure.
Can't think of any other important info. System data follows.
