[COLUG] Memtest86 causes reboot??

[Joshua.Kramer]

Howdy All,

My fiancee has a Dell E1505n (the one that shipped with Ubuntu 7.04) and 
had been working well until recently.  These symptoms started happening 
about a week or two after upgrading to Ubuntu 7.10.

Basically, the keyboard stops working.  That includes ALL of the keys, 
including the blue Fn keys.  (Those have always worked, even when X was 
locked up)

Upon a reboot, there is a long series of beeps and the keyboard still 
doesn't work.

After a 24 hour wait (!!), the keyboard works again.

For kicks, I picked the Memtest86 menu item.  At approximately 8% complete 
(that is, 8% of the tests), the laptop rebooted, and the keyboard is 
locked up again.  (Last time this happened she had about two days' of use 
before the problem cropped up again.)

I don't have a USB keyboard lying around to see if this is a keyboard 
issue or a memory/motherboard issue.

Should Memtest86 cause a reboot?  The built-in Dell diagnostics don't 
indicate a problem...

Thanks,
J
