[ale] Something blew up -- but what

Sat Nov 17 17:35:48 EST 2012

One sure fire way to guarantee confusion is to change two things at the 
same time.  I'm supposed to know better! :(

This mobo has two pair of memory slots. First slot in each pair had a 1 
gig memory module. Today I added more memory and now the first slot of each 
pair has a 2 gig module and the second slots each have the older 1 gig 
module.

Computer (FC-13) booted just fine.  Recognized the new memory.

Also replaced an aging CRT with a new monitor (Asus PA248) w/ 1920/1200 
resolution. Vast improvement.

Then I am enjoying the new monitor by viewing scenic vistas I shot this 
summer when the keyboard & mouse lock up completely.  Have to hit the 
power button on the box -- which I know is not a good thing to do.

Below is the appropriate section from /var/log/messages.

Can anyone shed any light on what might have caused the keyboard/mouse to 
lockup?  I'd guess it's video related, but that's just a guess.

Sean
