I'm found it in the system log and don't know, how it happens, and how to reproduce. :)
System works normally.

Comment 1 LiorD 2009-01-20 16:30:58 UTC
This is a warning not an oops so it's less serious :)

This thread seems related http://lkml.org/lkml/2008/8/13/63
You can try the patch there and see if it works for you as well.
Comment 2 Mike Pagano gentoo-dev 2009-02-05 14:59:18 UTC
Can you please test the latest git sources which is 2.6.29_rc3-r7. The patch referenced in the previous comment is in that kernel as well as vanilla-sources-2.6.29_rc3.

Thanks.
Comment 3 Mike Pagano gentoo-dev 2009-02-22 19:56:21 UTC
Please reopen when you've had a chance to test as requested in comment #2
