It seems unlikely that fsck is going to help. The BUG_ON in question
appears to be:
BUG_ON(inode->i_data.nrexceptional);
This is an in-memory accounting variable which seems to be related to
tracking DAX and shadow page entries --- and it seems very unlikely to
be the sort of thing triggered by an on-disk corruption.
Do you have a reliable repro for this? If so, the next step would be
to bisect...
