Please attach full dmesg output with that call trace.
Created attachment 51412 [details] I copied this from Launchpad report, no errors on the dmesg file, only on kern.log
It's great that the kernel bugzilla is back. Can you please verify if the problem still exists in the latest upstream kernel?
Hello, welcome back This bug is no more reproducible, I think the fix was in the 3.0 series. Thanks Fabio
