Dear Maintainer,

I have just upgraded from kernel on testing (4.9.13) to the version on
unstable just to test it, the version on testing was running fine.

The machine is running testing and is fully up to date with it. I had not
noticed any problem till now.

What I saw after upgrading to 4.9.16 and rebooting was that X came up in a
low resolution mode, not 1920x1080 like it used to. The keyboard and mouse
(both usb) were stuck, while the machine was still alive through network, so
I assume that X were stuck at that time.

The information that comes here is the one gathered booting in rescue mode.
I'll try to add the X log and more info in a later mail.

Regards.

Hi!

I later discovered what the problem was when I tried to get my net up in
recovery mode and couldn't load the right modules. Looks like somehow I
ended up with a bad or nonexistant modules.dep or modules.dep.bin or
similar, the fact is that the kernel modules were not loaded, this seems to
be what caused all the trouble.

Running modprobe -a from the new kernel on recovery mode solved all the
problems and X is working ok right now as well as the mouse and the
keyboard, so everything looks fine.

So... trying to see what had happened I came up with this...

I had installed linux-image-4.9.0-2-amd64/testing and did:
apt-get install linux-image-4.9.0-2-amd64-unsigned/unstable
which removed the kernel from testing and left the configs around.
I later purged the configs from the kernel from testing with dpkg --purge
installed the headers from the new version and rebooted.

I believe that it was the purge that messed the depmod info.

I don't know if we should close the bug or we should investigate more on
what happened. If you want me to investigate anymore just let me know.

Regards.

We no longer build linux-image-*-unsigned packages, which effectively
fixed this bug.
