Sorry for the late reply.

The weird part is, the access beyond boundary happens for read, no
wonder why previously added debug for discard doesn't work.

Currently I have no idea at all.

BTW, have you tried "btrfs check --check-data-csum"?
Regular btrfs check only check metadata but not data.

Considering how many the beyond boundary read there are, it looks like
some thing wrong related to data, thus "btrfs check --check-data-csum"
may help.

Another idea is to rule out memory corruption by running memtest, but I
doubt if it's the case.

Thanks,
Qu
