>Description:
after upgrade from 6.2-p9 to 7.0-release, my system freeze sometimes
(full freeze, mouse and keyboard dont answer, network freeze too) for a
little time (from 3 to 40 seconds). i read kernel output and see this:

my device is a wireless netcard 'Planet WL8310V3'. i try to change
interrupt in my bios - no changes.
>How-To-Repeat:
i think problem with 'ar5212' chip, so insert 'ar5212'-based card on
7.0-release.

 Try unloading the wlan_amrr kernel module. I suspect that is where the 
 problem is.
