Does your kernel config include the softlockup detector? If you could please do sysrq-w and sysrq-t while it is locked, it'll help us track it down. It will be much easier if you have a serial console or network console, and you've increased your kernel logging level to the highest value (dmesg -n7) -chris -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
