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. https://admin.fedoraproject.org/updates/kernel-3.1.0-0.rc3.git0.0.fc16 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. |
Created attachment 519053 [details] 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): kernel-3.0.1-3.fc16 How reproducible: Happens maybe 1/10th when there is unclean shutdown of filesystem. Steps to Reproduce: 1. Crash system during disk activity. 2. Reboot Actual results: Fails to mount btrfs filesystem Expected results: Btrfs recovers its log and allows file system to be used. Additional info: 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.
