Subject: oops in kernel ( 3.4.x -> 3.5rc )

Hello,
Since i 've updated our server from linux kernel 3.3.8 to linux kernel
3.4.6 or linux kernel 3.5rc7,
we can observe a lot of oops and big load  on system.

Example : Linux positronic836 3.5.0-rc7 #4 SMP Fri Jul 20 11:47:12 UTC
2012 x86_64 Intel(R) Xeon(R) CPU E5345 @ 2.33GHz GenuineIntel
GNU/Linux

Regards,
Nicolas Prochazka.
