Hrm, wonder what's causing the IO errors... I did fix the reboot notifier the other day, can you try either my bcache-for-3.10 or bcache-for-3.11 branches? That should fix shutdown and reboot. Suspend and hibernate should be fixed in the for-3.11 branch, but I think I'll need to backport a freezer fix for it to work in 3.10... -- To unsubscribe from this list: send the line "unsubscribe linux-bcache" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
