Please see if you can reproduce this bug with the 2.6.40 update.

Comment 2 Patryk Obara 2011-08-16 08:44:54 UTC

I was not able to reproduce it after reporting this one; I had completely no oopses since update to 2.6.40.

Comment 3 Josh Boyer 2011-09-26 18:19:23 UTC

Thank you for letting us know!
