Just installed Linux Mint 13 (the Cinnamon version) a few days ago and everything was working great, but suddenly i can't do a clean shut down. Everytime i do it, i get long lines of text an the system never recovers of it, gotta force a shutdown holding the button. There are long lines of text moving fast but i spotted a few lines:
Watchdog detected hard lockup on CPU 0 (an later CPU 1, 2, 3, etc.)
Bug: unable to handle kernel paging request
don't know how to fix it. Im using a Dell Inspiron 620
Intel® Core™ i5-2320 CPU @ 3.00GHz × 4
HD 1.5 TB
Linux Mint 13, CInnamon, 64-bit
I'll appreciate any help.
