Kernel crash related to LZO compression

[Dmitry Katsubo <dma_k@mail.ru>]

Dear btrfs community,

My excuses for the dumps for rather old kernel (4.9.25), nevertheless I 
wonder
about your opinion about the below reported kernel crashes.

As I could understand the situation (correct me if I am wrong), it 
happened
that some data block became corrupted which resulted the following 
kernel trace
during the boot:

kernel BUG at 
/build/linux-fB36Cv/linux-4.9.25/fs/btrfs/extent_io.c:2318!
invalid opcode: 0000 [#1] SMP
Call Trace:
  [<f8c63739>] ? end_bio_extent_readpage+0x4e9/0x680 [btrfs]

  [<de084030>] ? kthread_park+0x50/0x50
  [<de5aae03>] ? ret_from_fork+0x1b/0x28

The problematic file turned out to be the one used by systemd-journald
/var/log/journal/c496cea41ebc4700a0dfaabf64a21be4/system.journal
which was trying to read it (or append to it) during the boot and that 
was
causing the system crash (see attached bootN_dmesg.txt).

I've rebooted in safe mode and tried to copy the data from this 
partition to
another location using btrfs-restore, however kernel was crashing as 
well with
a bit different symphom (see attached copyN_dmesg.txt):

Call Trace:
  [<f8b4c760>] ? lzo_decompress_biovec+0x1b0/0x2b0 [btrfs]

  [<d70840e4>] ? kthread+0xb4/0xd0
  [<d75aae03>] ? ret_from_fork+0x1b/0x28

Just to keep away from the problem, I've removed this file and also 
removed
"compress=lzo" mount option.

Are there any updates / fixes done in that area? Is lzo option safe to 
use?

P.S. Perhaps relative issue is in "Warnings" section:

https://wiki.debian.org/Btrfs#Warnings / 
https://www.spinics.net/lists/linux-btrfs/msg56563.html

With best regards,
Dmitry
