Control: retitle -1 Boot fails due to missing ext4 module

Can you clarify how far the system boots?  Does it stop at a shell with
the prompt '(initramfs)'?
Stops at: "maintenance mode. Give root password or control-D"
Oh, so this is not an initramfs problem as I suspected.

Frankly, I woulnd't tell.




And I think, it does that because /srv/pgdat is ext4 and cannot be
mounted because of missing ext4.ko within the kernel.

Then I think the package is not properly installed.

Naturally "someting is wrong". But since the wheezy to jessie upgrade, there was at least one time the kernel was updated too. And the problem remains while the update didn't complain about anything.

In any case, first thing I did (after reviving the system to the point I had a usable /usr) I did "apt-get install --reinstall" both kernels. No errors reported. Something really strange did happen on the moment of transition from wheezy to jessie. But I'm lost guessing which package to blame (apart from ext4, my notebook keyboard stopped working then, it works only when I boot i485 kernel - the one without ext4 - and only when I boot it with sysvinit scripts, otherwise it's dead). My best guess is that the problem has something to do with the kernel. May be the load order of modules?? Boot screen shows two red "FAILURE" lines (somewhat apart from one another) reporting something along the lines of "unable to load module", but dissapears quickly and isn't copied to neither dmesg nor kern.log nos syslog.


Do these commands produce any output?

     debsums -c linux-image-3.2.0-4-486
     debsums -c linux-image-3.16.0-4-586

both report OK (echo $? --> 0).

If not, does modprobe start working if you run 'depmod' first?

no, it didn't. (although I can see /lib/modules/3.2*/modules* files were touched).

And a direct "insmod /lub/modules/3.2.*/kernel/fs/ext4/ext4.ko" doesn't work either.
