Title:
kernel BUG at /build/buildd/linux-2.6.38/fs/btrfs/disk-io.c:2349!
Status in linux package in Ubuntu:
Won't Fix
Bug description:
I format USB-flash-drive to btrfs, mount it to /media/something. Then I
extract USB-flash-drive (while it still mounted). Next second kernel oops
happens.
After reboot (and auto-mount USB-flash-drive) I extract it once more (not
unmounting), black screen and kernel oops.
Then I format it to ext4, mount and extract, all ok. So only btrfs affected.
