--- Comment #6 from Leandro Lupori <leandro.lupori at gmail.com> ---
Looking at the latest version of vfs_bio.c, it seems all these parts are now
using only mp_maxid.
bd_flushall loop has also been changed to go up to i <= mp_maxid, instead of i
< mp_maxid.
Still, the issue persists.

Also, by adding only the bdomain array (and corresponding structs'
declarations) in the previous commit, that was working, the issue happens.

The two triggers to this issue seems to be:
- set usefdt=1
- change kernel memory layout
