Comment 2 Andrew Morton 2009-04-22 21:12:09 UTC 
I'll assume that 2.6.29 didn't have this bug.
Comment 3 Thomas Meyer 2009-04-22 21:34:24 UTC 
Yes. 2.6.29.1 is fine. I also set above regression flag to yes to indicate this situation.

This should fix the crash. Its on its way upstream and should hit Linus' tree in the next networking merge.
