Hi Qu!
Is there any chance to find some hints of the issue in the log I attached?
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

Hi Qu!
It happened again, and this time I've been able to dump the dmesg.
Also this time it happened on my home drive, please see the attached dump.
What can I do to fix it?
btrfs scrub reports no error, neither does brfs check.
I have also remounted the partition with -oclear_cache,space_cache, I
hoped that could fix it...
Thanks...
