Yeah I thought that, too, because after hitting "reset" it looked like one hard disk didn't appear in dmesg and thus btrfs didn't mount (btrfs-raid). So I turned the machine off completely because I had similar issues with i915 freezes and strange boot issues during the following boot before. It looks like the GPU is not necessarily completely reset when hitting the reset button. But that's another story. In my case the hard disk was there - I didn't just scan hard enough through the huge pile of logs. I had to btrfs-zero-log, wrote "reboot" into the rescue shell, kernel came back, mount still locking up and sitting there until systemd decided to throw me to emergency after 5 minutes of waiting or so. I've rebooted again, machine came up. This was a few reboots after the machine was powered off, so I'd rule any GPU freeze artifacts out here. I just needed multiple reboots to arrange myself with my dracut/systemd combo super hero voodoo abilities (read: I cumbersome tried everything until one thing worked while swearing at my innocent monitor, well sort of, it's powered by the GPU). On every reboot it felt like bcache was replaying cache transactions - but I think this is by design (read: bcache is always dirty, even after a clean shutdown, if using write-back mode) and not part of the problem. -- Replies to list only preferred. -- 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
