Subject: Ext4 Recovery: Invalid checksum recovering block # in log

Hi!

After an unclean "shutdown" the system hangs when mounting the filesystems.

When I remove the affected ext4 drive from fstab the system starts and I can further investigate.

Try to mount: syslog is flooded with
JBD2: Invalid checksum recovering block 1152 in log
(always the same number, it doesnt seem to stop filling the log file)

Run e2fsck: console is flooded
JBD: Invalid checksum recovering block 1152 in log

debugfs gives an additional message:
Block bitmap checksum does not match bitmap while reading block bitmap
(But the filesystem is not opened, so logdump is not working.)


Any help is highly appreciated. (I have not found this issue online.)

Thanks,
Markus
