Default ACPID stuck in an endless loop - prevents login

Hi all.

After a recent Debian update, I've been unable to log in to my
Debian/Linux server using the console and GDM3 won't start - X.org
crashes part way through the startup.


I think ACPID may be the cause because in syslog there is an endless
repetition of the same messages every few seconds. Below is a sample.


Login through SSH still works. If I stop the ACPID daemon, the messages
go away and the machine settles down. Logins work again but GDM3 is
still messed up - it is trying to start over 100 X sessions repeatedly
and as each fails, it tries again.


Anyone have any idea what is going on here?

Thanks.

What can be read from X server error logs?

(you can boot from single-user mode and work from there)

Mmm... my wild guess is the X server is crashing and makes "acpid" going
nuts.

The mga driver is not loading because it thinks a kernel module is
already using it.


[ 1223.466] (EE) mga: The PCI device 0x525 at 01@00:00:0 has a kernel
module claiming it.
[ 1223.466] (EE) mga: This driver cannot operate until it has been
unloaded.


Is there a way to find out what is using it?

Thanks.

Gosh, what a cryptic message :-?

I have the feeling it is related to this patch:

http://lists.fedoraproject.org/pipermail/scm-commits/2012-May/785807.html

I can't really decypher the meaning, sorry, let's see what the X gurus can tell
you :-)

A shoot in the dark: you can try by passing to the kernel line the
"nomodeset" parameter from GRUB's boot menu.

Greetings,

What can be read from X server error logs?

The mga driver is not loading because it thinks a kernel module is
already using it.

(thanks for sending the log)

[ 1223.466] (EE) mga: This driver cannot operate until it has been unloaded.

Is there a way to find out what is using it?




Did some more digging and found out that one of the Matrox kernel
modules was blocking the X.org mga X server from starting. The module
causing the problem is called "matrox_w1". Don't know what it is used
for, but as soon as it was blacklisted, X started cleanly and the
endless loop problem seems to have stopped.


I think I'll file a bug with Debian about it. This must be a recent
problem.


Thanks for your help, Camaleón.
