Hi folks.
Yesterday I updated kernel to 5.2 (git commit 7e9890a3500d)
I always leave computer working at night.
Today at morning I am found that computer are hanged.
I was connect via ssh and look at kernel log.
There I had seen strange records which I never seen before:

[28616.429757] EXT4-fs error (device nvme0n1p2): ext4_find_extent:908:
inode #8: comm jbd2/nvme0n1p2-: pblk 23101439 bad header/extent:

[28616.432692] EXT4-fs error (device nvme0n1p2):
ext4_journal_check_start:61: Detected aborted journal

After reboot computer and running fsck system looks like working.
But I am afraid that it could happens again and I may lost all my data.

How safe this error and what does it mean?
It a bug of kernel 5.2 or not?
