--- Comment #3 from Andrey Lelikov ---
I also experience same behaviour. The system is unbootable. Please note, that i
do NOT have journal_checksum in fstab. On a kernel that works I have the
following:
/etc/fstab:
/dev/mapper/root_crypt / ext4
errors=remount-ro,data=writeback,noatime,nobarrier,journal_async_commit,commit=120,dioread_nolock
/proc/mounts:
/dev/disk/by-uuid/a3dc1a73-42b9-4295-b0b0-93934b57d317 / ext4
rw,noatime,dioread_nolock,journal_checksum,journal_async_commit,nobarrier,errors=remount-ro,commit=120,data=writeback
On 3.18 (ubuntu trusty) I can't boot any way - regular boot fails to mount,
mount -o remount doesn't work with any options - with or without
journal_async_commit and/or journal_checksum.
Note that on 3.13 everything works, all flags are properly applied and they are
NOT silently ignored.
So this is a bug, but it is yet in denial stage. "remove journal_checksum from
fstab, or add it to rootflags, everything works, la-la-la". Pedantic idiots.
