It seems that something is causing panic's on some of our test beds. At
first sight it appears to be something slab related (alloc_slabmgmt). I
had a quick look at what had been added in -mm3 (as -mm2 is ok) but the
only things that jumped out really didn't want to be backed out.
Any suggestions as to what I should try?
-apw
Checking if this processor honours the WP bit even in supervisor mode... Ok.
