Hi Qu,
thank you, but unfortunately that didn't work out so well. The tree
dump was no problem [1], but clearing the space cache resulted in a
core dump. Now btrfs check --readonly reports some errors. I attached
the output of these commands.

Meanwhile I upgraded to kernel 5.0, but the problem remained the same. So I
zeroed the log with btrfs rescue zero-log. The command was successful, however
the problem still remains more or less the same, which means:
- I still get a kernel oops when mounting.
- The stack trace looks a bit differ
Hi.
Yesterday when powering off my PC systemd's umount service run in a timeout.
Today linux couldn't boot anymore, instead I suddenly found myself in the
kernel's rescue shell. Seems like btrfs is broken on my root partition.
# mount -t btrfs -o ro /dev/nvme0n1p3 /mnt
...produces a kernel oop
