dmesg log of BUG on unplug

Details in the dmesg output; this does not happen on F12's 2.6.32.11-99.fc12.x86_64, but does happen on F13's 2.6.33.2.  Test system is a stock Fedora 13 Thinkpad T42 (32-bit only).

See https://bugzilla.kernel.org/show_bug.cgi?id=15917 for throttling issues and a slightly different bug.
Comment 3 Dan Williams 2010-05-05 23:51:07 UTC 
Yay, URB double-frees everywhere!  Fixing...

I've also got another patch that fixes the "don't map memory from the stack BITCH" warning thats in this log too.
Comment 4 Andrew Morton 2010-05-06 21:08:17 UTC 
blah, too many bug reports.

Rather than having me bounce all this stuff to the USB list, could I suggest that you prepare a jumbo bug report and email it to linux-usb@vger.kernel.org?
Comment 5 Dan Williams 2010-05-06 21:23:48 UTC 
Sure, can do.
Comment 6 Greg Kroah-Hartman 2012-02-22 21:10:45 UTC 
All USB bugs should be sent to the linux-usb@vger.kernel.org mailing 
list, and not entered into bugzilla.  Please bring this issue up there,
if it is still a problem in the latest kernel release.
