I was able to get my laptop back on line by booting from a live desktop disc, and then running 'btrfs-zero-log' on the affected hard drive partition. I assume the bug in the btrfs kernel module is still present. I'm sure a developer could reproduce it by first setting up the netconsole, and then starting a download and holdin down the power button to make it shut off during disk activity to the SSD. Hopefully the full "kernel BUG" message will be sent over the netconsole. I'm sorry I did not make a filesystem image, etc. I have work to get done with this laptop, and very little time to try and help debug it.
Because I have most of the syslog logs turned off, and the crash happened before it can mount the root filesystem anyway, there will be no logs to gather. This is as complete as this bug report will get, I think. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1102275 Title: kernel BUG at /build/buildd/linux-3.5.0/fs/btrfs/tree-log.c:3257!
