Troublesom info shutting down the computer

From: Garrett Gaston 
------------------------------------------------------
My desktop (Mint Linux) has recently started giving me that black and white=
 screen with all the bullshit when I shut it down. It's hard for me to catc=
h everything but here's a few things I got written down in time.

-> Asking all remaining processes to terminate.

-> Watchdog detected hard LOCKUP on cpu 0.


Any ideas?

=============================================================== From: William Wade ------------------------------------------------------ Often you can see the result of that in a log file. Check /var/log/syslog (as well as syslog.[0,1]) (Mint might use /var/log/messages not sure) Easy way to test is $ cat [filename] | grep lockup

=============================================================== From: James Nylen ------------------------------------------------------ Add -i to that command since you wrote LOCKUP in caps: cat filename | grep -i lockup
