kernel console output on crash
Description of problem:
Sometimes after a system crash (I'm running nouveau on barely supported hw) btrfs fails to recover its log.
Unfortunately btrfs is my root filesystem and this then makes F16 unusable.
Version-Release number of selected component (if applicable):
Happens maybe 1/10th when there is unclean shutdown of filesystem.
Steps to Reproduce:
1. Crash system during disk activity.
Fails to mount btrfs filesystem
Btrfs recovers its log and allows file system to be used.
To recover I have now twice booted to F15 live disk and mount the filesystem. The older kernel does not crash on the journal and after next boot I can boot back to F16.
This is fixed in the most recent kernel. I've submitted the patches to -stable so it should show up in a stable kernel at some point, but until then you can run the latest rawhide kernel and I think the patches are in there.
Should be fixed in 3.1.0-rc3
kernel-3.1.0-0.rc3.git0.0.fc16 has been submitted as an update for Fedora 16.
kernel-3.1.0-0.rc3.git0.0.fc16 has been pushed to the Fedora 16 stable repository. If problems still persist, please make note of it in this bug report.
