'Crashed' today, but no traces were produced because aparently xfs and
btrfs (both aren't even used) modules have 'bad taint':

| xfs: module has bad taint, not creating trace events
| btrfs: module has bad taint, not creating trace events
| EXT4-fs error (device vda1): ext4_mb_generate_buddy:756: group 75, 11202 clusters in bitmap, 11200 in gd; block bitmap corrupt. 
| Aborting journal on device vda1-8.
| EXT4-fs (vda1): Remounting filesystem read-only

Also, this is vda1, not vdb. vda1 is my root fs and is only 10GB in
size.
