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...
