sounds like adding mdelay() didn't help to crash it sooner. Then I don't see how my dst fix was causing it to crash more often. Something odd. fyi just to check it more thoroughly I've been running with mdelay() and config_slub_debug_on for a week without issues.

try config_slub_debug_on=y ? it should catch double free and other things.
