LinuxMint 14 Cinnamon 32bit and 64bit freeze

I'm seeing the exact same issue on Linux Mint 14 Cinnamon 32 bit on my dell XPS M1210. I've faced this issue 5 times in past 1 day. Every time I'm using Firefox when the screen freezes (mouse works fine) and then I hit Ctrl+Alt+F1 and check top. Cinnamon process is hogging the CPU 100%. I have to reboot every time.

Having the same problem here. Locks up for 3-4 minutes. Sometimes it recovers and asks for my admin password, other times it reboots itself. Running on Dell inspiron 1720. I was so happy to come back to linux now that I can get my broadcomm wireless to work!

Can you please try changing the power settings and see if this still occurs?

This is happening on my recently upgraded linux mint 15, 64 bit installation, cinnamon version 1.8.8, and it's getting worse. I can launch a terminal though with ctrl-alt-T and then I can run cinnamon --replace.

That will restart cinnamin with an error, namely
DBus.Error:org.freedesktop.PolicyKit.Err.Failed: An authentication agent already exists for the given subject.

I get a cinnamon panel and window freeze especially after any idle period. The symptoms are similar so I presume it's related.

And almost one year later....

This affects me too on two different Dell Optiplexes. One with Mint 17 and the other with Mint 15. The crashes seem to happen independently of what I'm doing.

On my Mint 17 one of three crashes this morning happened a short while ago:

This happened to me, one time before it had been on for a minute, and the next the computer had been on for 5 minutes.
Mouse moves but won't interact,
Keyboard is dead.

Opened in recovery mode and everything was fine,
Nothing wrong on file checker,

Did normal boot: it's worked for half an hour.

Does this still happen on Rebecca? MDM was updated, so it may have been fixed?

I am still having this issue on Mint 17.1 Cinnamon 64 bit with the latest updates. I have an Acer laptop with 2nd gen Intel Core i7 and intel graphics. It seems to happen less lately, and it also seemed to be related to resuming from sleep mode, although that works most of the time. Usually when I get a freeze, I can use the magic SysRq REISUB command and reboot, but sometimes that doesn't even work, forcing a hard shutdown.

I'm considering moving to LMDE 2 at this point to see if this has been fixed, but just haven't had time to test yet.
