That might be worth filing a PR for, especially the panics.

Exactly what is damaged? Garbage in files? Wrong inode counts? I've had
unclean filesystems because of panics, but nothing fsck_ffs couldn't
fix.

You might want to check the hardware too. Use smartmontools in case of
(S)ATA drives.

Smart says that the drives are fine, as does the manufacturer's disk
fitness tools.

That's at least some good news.

At least these files should be easy to replace, if necessary.

fsck_ufs dies after about 30 minutes of grinding with the following:

UNEXPECTED SOFT UPDATE INCONSISTENCY

Did these problems start after a crash?

SALVAGE? no

What happens if you tell it to try and salvage?
