It's kmalloc, at least this is how I think skbs are allocated. Andrew, I don't have access to PPC hw right now (doing MIPS development these days), so I cannot quickly check that my theory is still correct for the latest kernel. I'd wait for the reporter to try my hack and then we can decide what to do. IIRC there was some provision in slab allocator to enforce alignment, when I was debugging this problem more then a year ago, that option didn't work. BTW, I think slob allocator had the same issue with alignment as slab with enabled debugging (at least at the time I looked at it).
Hello Eugene, In case you didn't notice yet, I have added the following comment to the kernel bugzilla item: ------- *Comment #5 <http://bugzilla.kernel.org/show_bug.cgi?id=8778#c5>From Bart Van Assche <[EMAIL PROTECTED]> 2007-07-18 07:12:49 * [reply<http://bugzilla.kernel.org/show_bug.cgi?id=8778#add_comment>] ------- I have downloaded the patch from http://kernel.ebshome.net/emac_slab_debug.diff, and I have tried it. Hereby I confirm that this patch solves the reported kernel oops. -- Regards, Bart Van Assche.
