Hi, I've been running btrfs fine on my Sheevaplug (ARMv5) for a few months. However, last night, using kernel 2.6.34, I got repeated reboots, with many traces like this in the logs:

Let me know if you want me to run any btrfs commands for more debug information. Many thanks, Jonathan. -- To unsubscribe from this list: send the line "unsubscribe linux-btrfs" in the body of a message to majord...@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
