Looks like ext4 bug:

[ 1916.032087] EXT4-fs error (device sda): ext4_find_extent:909: inode #8: comm jbd2/sda-8: pblk 121667583 bad header/extent: invalid extent entries - magic f30a, entries 8, max 340(340), depth 0(0)
[ 1916.073840] jbd2_journal_bmap: journal block not found at offset 4455 on sda-8
[ 1916.081071] Aborting journal on device sda-8.
[ 1916.348652] EXT4-fs error (device sda): ext4_journal_check_start:61: Detected aborted journal
[ 1916.357222] EXT4-fs (sda): Remounting filesystem read-only

So best place for report is likely linux-ext4@vger.kernel.org
