Comment 3 Alan Stern 2006-01-15 08:34:34 UTC
It's entirely possible that this is not a USB problem.  I get the impression
that the fault occurred at the line in driver_del() where
platform_notify_remove() is called.  You can try commenting out that call, and
maybe sprinkling some printk statements throughout the region to see how if that
really is the problem.
Comment 4 Greg Kroah-Hartman 2006-01-16 10:21:09 UTC
Does this happen with 2.6.15 or 2.6.16-rc1?
Comment 5 Oleksij Rempel (fishor) 2006-01-16 12:49:17 UTC
> 2.6.16-rc1  
I don't know any thing about this kernel, is it already out?  
> 2.6.15 - 2.6.15-mm3 ? 
No. Only 2.6.15-mm4 
Comment 6 Greg Kroah-Hartman 2006-01-16 13:11:03 UTC
Will be in a day or so.

How about 2.6.15-git12?
Comment 7 Oleksij Rempel (fishor) 2006-01-17 05:26:58 UTC
Latest git or 2.6.16-rc1 is working. 
Comment 8 Greg Kroah-Hartman 2006-01-17 07:46:25 UTC
Great, marking closed then.
