And this seems to have helped. The host doesn't crash any more (with the 15.2 stock kernel).
Eh, too bad, it was supposed to catch the culprit, not prevent the bug from manifesting by changed layout/timing... Let's try being more specific about the debugging and limit it only to suspected caches. What happens if you boot with just this parameter? slub_nomerge And then, cat /proc/slabinfo | grep biovec, is the output like this? gehinom:~ # cat /proc/slabinfo | grep biovec biovec-128 272 272 2048 16 8 : tunables 0 0 0 : slabdata 17 17 0 biovec-64 544 544 1024 32 8 : tunables 0 0 0 : slabdata 17 17 0 Then try booting N times with a special parameter for each biovec-X in the list above, e.g. in my case, 2 times: slub_nomerge slub_debug=FU,biovec-64 slub_nomerge slub_debug=FU,biovec-128 Thanks. -- You are receiving this mail because: You are the assignee for the bug.
