You forgot to enable DEBUG_PAGE_ALLOC again, but I don't think it much
matters. It's another slab free poison thing.
The faulting instruction is
mov 0x28(%rbx),%ecx
with %rbx having the value 6b6b6b6b6b6b6b6b.

That seems to be
if (hash != sd->s_hash)
from sysfs_name_compare() that has been inlined into
sysfs_find_dirent(). And where "sd" is the corrupted value. If I read
things right.
So it looks like the sysfs rbtree is corrupted or something. Adding
