enabled. With that kernel configuration I was unable to
reproduce the problem during 500 typical workload / reboot
cycles. Without the debug options I was able to reproduce the
last reported panic after 91 cycles. The debug options seem to
change timing sufficiently to mask the bug ;-(
It has all DEBUG_OBJECT options enabled:
# CONFIG_DEBUG_OBJECTS_SELFTEST is not set
but it also has DEBUG_PAGEALLOC enabled:
I'd suggest disabling that one - it kind of overlaps debugobjects
and it will definitely be a big slowdown.
I'd also suggest turning off lockdep for now:
because we know it does not trigger any useful warning. This too
should speed up things a bit.
Whether this would make the crash reproducable again I don't know
