Well, that's a little bit of info.  One bit is that you have 768MB of
RAM but only 512MB of swap.  That isn't the cause of the panic, but it
prevents a panic dump from being written to /dev/swap, and that makes
further debugging difficult.

You got a trap E at kernel code address 0xF00E11D9 (eip), due to a
reference to address 0x00000040 (cr2).  Now run:

  # echo ts F00E11D9 | crash
  # echo dis F00E11D9-20 20 | crash

and post the results.

Many of the products and books I review are things I purchased for my own use. Some were given to me specifically for the purpose of reviewing them. I resell or can earn commissions from the sale of some of these items. Links within these pages may be affiliate links that pay me for referring you to them. That's mostly insignificant amounts of money; whenever it is not I have made my relationship plain. I also may own stock in companies mentioned here. If you have any question, please do feel free to contact me.

Specific links that take you to pages that allow you to purchase the item I reviewed are very likely to pay me a commission. Many of the books I review were given to me by the publishers specifically for the purpose of writing a review. These gifts and referral fees do not affect my opinions; I often give bad reviews anyway.
