it seems to be the same problem in 9.3 with the atmel driver.
Please have a look at bug #90649.

I will add a attach with the whole output of dmesg

Created attachment 45390 [details]
output of dmesg
Comment 2 Greg Kroah-Hartman 2005-08-10 18:36:33 UTC 
Ah, this isn't an "oops", it's just a WARN.

Please fix the driver as it says to do so.
Comment 3 Joachim Gleissner 2005-08-25 09:25:22 UTC 
I'll add a patch.
Comment 4 Joachim Gleissner 2005-09-02 12:46:28 UTC 
The badness messages should be gone with beta4.
