intel_idle kernel panic on startup

impiaaa · 2012-10-25 19:43:02

I don't know what caused the breakage, but I get this kernel panic whenever I boot my computer:

If I disable systemd from the kernel parameters, I can get to a login prompt, but GDM won't start.
Any ideas on where I should start looking for solutions?

Can you explain "GDM won't start" if systemd is disabled? Does this kernel panic happen every time the computer is started up with systemd enabled? Try disabling it, trying to start gdm (via command line, not automatically) (does it get errors?), then check /var/log/Xorg.0.log and dmesg for any possible errors (and post them here).

Did you upgrade to systemd from initscripts? Or is this a fresh install with systemd stock from the new release?

You can also try to boot with systemd disabled, remove gdm from auto startup, reboot and see if it still happens (if its a problem with your gdm/gnome setup).

I can confirm this. Happens sometimes on my T420s on boot or shutdown. Unfortunately I can not say which update introduced this since I reinstalled arch recently.

I was mistaken. It does start, it just didn't work at first because dbus wasn't started.

It's a hybrid upgrade. I kept an rc.conf because bumblebee doesn't have a systemd profile, but all other daemons are started directly (not legacy).

So if I have to revert to initscripts, is there a way to find out what daemons I had enabled in systemd? I can't use systemctl since systemd isn't on.

Standard bumblebee package from the AUR does have Systemd support. /Offtopic

Huh, okay. Maybe I was thinking about bbswitch? Anyway, I'll take a look once I figure out how to fix my current problem.

So, I switched back to initscripts (I found out I still had my old Daemons array commented out), and I can boot up now, but I just got this after waking up and trying to log in:

It appears to be the same one as before. So, that leads me to believe that it's not a problem with systemd. Where can I start looking for the real origin of the problem? Is it possible this is a bug?

Well then, it looks like I'll have to upgrade somehow. Does anybody have any ideas? Is a complete re-install the best option at this point?

Edit: Never mind, it fixed itself.

Somehow.
