You also have the 'P' taint for a proprietary module loaded, so we (upstream) can't really help with that, you're better off reporting to your distro. If it's easily reproducible you could boot with slub_debug=FZP and see if that catches the slab corruption earlier, that might help us identify the actual problem. cheers
