[trying again, this time with correct kernel.org address] Hi, I have seen the following and similar problems several times, with both v4.19.3 and v4.19.4: Nov 23 04:32:25 mars kernel: [112668.673671] EXT4-fs error (device sdb1): ext4_iget:4831: inode #12602889: comm git: bad extra_isize 33661 (inode size 256) Nov 23 04:32:25 mars kernel: [112668.675217] Aborting journal on device sdb1-8.

Nov 24 01:52:31 saturn kernel: [189085.275313] EXT4-fs (sda1): Remounting filesystem read-only The same systems running v4.18.6 never experienced a problem. Has anyone else seen similar problems ? Is there anything I can do to help tracking down the problem ? Thanks, Guenter
