Thanks. CONFIG_PROVE_LOCKING=y would be useful, if you didn't already have it set. Also after the kernel has failed, kill everything off and do a `ps aux' and look for any other tasks which are stuck in "D" state. Backtraces for any such processes can be obtained with "echo w > /proc/sysrq-trigger". -- To unsubscribe, send a message with 'unsubscribe linux-mm' in the body to majordomo@kvack.org.
