Here is a link to the upstream patch, in case anybody wants to try it out: http://thread.gmane.org/gmane.comp.file-systems.btrfs/12319
A quick test reveals that it does fix this bug, I haven't done any further testing though. Be careful when trying out patches on filesystem drivers, but for anyone willing to take the risk here is a quick rundown of how to rebuild the btrfs kernel module: - unpack the kernel source (from the kernel-source package) and copy the header files (from the kernel-headers package) into the same tree - apply the patch or make any other changes you want - run make M=fs/btrfs (works for any other module directory too) - copy the compiled module to /lib/modules/$VERSION/updates/ - run depmod - reload the module -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/816770 Title: kernel BUG when mounting btrfs filesystem from read-only (R/O) media To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/816770/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
