VM complaining: consider bios upgrade...

[Fabio T. Leitao]

During the Ubuntu boot, if you get to see a Grub menu (with kernel options,
etc), can you try to run the Memtest86+ option (that will automaticaly go
into a blueish program with lots of information on the several RAM tests it
will start to run... and leave it running until it says it has completed at
least 2 PASS)

If you have got some bad RAM, it will most certainly accuse (and some how,
your Linux host have not been using the faultly address recently) -
hardware do crash also... - and the message on Memtest86+ will be PRETTY
OBVIOUS (RED CAPITAL LETTERS WITH A BUNCH OF HEXADECIMAL MEMORY ADDRESSES)

If you have no bad RAM, with will also list a short 0 ERRORS somewhere in
the middled/right side of the screen

To exit the Memtest86+, anytime during the tests, just press ESC, and your
computer should reboot (and hopefully back to OS)

If you do have a faulty RAM, try removing a DIMM (that are the name of the
RAM boards) a time, and test the rest again until you are sure there ones
installed are fully operational... you might need to buy another RAM if you
do find any broken ones
