Summary: isp1362-hcd BUG_ON crash on simultaneous USB ports transfer

Details:

isp1362-hcd driver is consistently crashing with a BUG_ON check if two USB devices are active on both USB ports. Crash is reproducible any time both devices (ex. 2 USB flash drives) simultaneously transferring data or during USB setup stage. The easiest way to reproduce:

1. Connect and mount a USD flash drive with one of the 1362's USB ports.

2. Start a large transfer involving mounted flash drive, for example:

dd if=/dev/zero of=/mnt/usbdrive/test bs=20M count=1

3. While the above transfer is in progress, plug another USB flash drive in the second 1362's USB port.

4. Wait for the crash; try again if not immediately reproducible.

Below is the tail of a debug trace for the crash:

Hi Roman,

What's your hardware platform? we don't have the hardware to reproduce it.

-Bryan

--- Robin Getz 2008-07-08 08:45:29

Roman:

It looks like that crash dump was from a PowerPC?

Sorry - we can't help with that. The best thought is to try NXP - who wrote the

driver, or Freescale - who support PPC.

--- Roman D 2008-07-08 19:23:35

Bryan, Robin,

Yes, the platform is PPC but with all due respect I do not believe the driver

in question is written by NXP. The one by NPX is not GPL and supports

isochronous transfers, see this plus many other comments around the net:

ozlabs.org/pipermail/linuxppc-embedded/2005-June/018892.html

I filed the bug here because

(1) ISP1362 driver in question appears to be unique to Blackfin project

(2) The bug reported does not appear to be platform specific with the only

pre-requisite having both USB ports wired on the chip.

--- Mike Frysinger 2008-07-15 02:30:44

as you say, you're using a PPC ... we support the Blackfin processor here and no

other hardware. if you're having troubles on a PPC platform, you'll have to

seek assistance elsewhere. sorry.
