Follow-ups

--- Mike Frysinger 2010-08-03 03:34:50

this is a bug in your board resources:

sysfs: cannot create duplicate filename

'/devices/platform/sl811-hcd.0/usb1/power/power'

most likely has nothing to do with alsa

--- Michael Hennerich 2010-08-03 05:45:30

> this is a bug in your board resources:

Hmm - I don't see any issues with the board resources here.

Are there any other messages before the crash.

What commands are executed, etc.

--- Michael Hennerich 2010-08-03 12:04:35

This bug is also seen with the ISP1362.

I tested linux-2.6.33.1 (svn rev 8464) and it is working there.

So it must be something we imported since svn rev 8464

--- Michael Hennerich 2010-08-04 06:43:55

This bug was imported with update to stable linux-2.6.34.1 (svn rev 8971)

After debugging the issue myself, and on the way to find who to blame for

this I found the same fix on upstream.

I really wonder why this hot fix doesn't went into linux-2.6.34.2?

Apply upstream:

USB: add missing "{}" in map_urb_for_dma

Obviously, {} is needed in the branch of

"else if (hcd->driver->flags & HCD_LOCAL_MEM)"

for handling of setup packet mapping.
