Had a thunderstorm a week or so ago that ended up taking out one of my machines
immediately after a Fedora 14 to 15 upgrade. This particular
machine has two btrfs's on it. An Intel SSD which holds /, and a HD that holds
/home and a few other partitions.
I was having issues mounting the btrfs on both disks at first, but rolling back
to a previous snapshot on / resolved that. I don't have a
snapshot to roll back to for /home, but have managed to find a kernel that
would mount it (f15 2.6.38.8, which I was then able to recompile
kernel 3.0.0-rc5, which will also mount it) However, it's just a F15 kernel,
since I rolled back my / partition to a snapshot from before
the upgrade.
I am still getting random kernel oopses and processes locking up, I would
appreciate any help in getting my system to a workable state. I
realize the data may be lost, but my main concern is to get this machine to
stop hanging at the moment.
