Can you recreate that without the vbox modules loaded?
Package: kernel Architecture: x86_64 OS Release: Fedora release 16 (Verne) Comment ----- I have an external usb drive that is formated with btrfs (no partition table). 1. Removed from computer A (I thought it was after it completed syncing, probably was wrong). 2. Inserted into this computer. 3. No popup, not automatically mounted. So removed it (physically, nothing to unmount since it wasn't mounted) 4. bam, got kernel BUG.
Alon, please open an f16 bug with the backtrace.

Package: kernel Architecture: x86_64 OS Release: Fedora release 16 (Verne) Comment ----- nothing special.
Bruno, can you still reproduce this ? Had this been hibernated at all ?
Fedora 15 has reached it's end of life as of June 26, 2012. As a result, we will not be fixing any remaining bugs found in Fedora 15. In the event that you have upgraded to a newer release and the bug you reported is still present, please reopen the bug and set the version field to the newest release you have encountered the issue with. Before doing so, please ensure you are testing the latest kernel update in that release and attach any new and relevant information you may have gathered. Thank you for taking the time to file a report. We hope newer versions of Fedora suit your needs.
