kernel error

[Albert Wagner]

I keep getting malfunctions where my screen goes black and the keyboard 
is unresponsive, necessitating hard reboot.  The following entries from 
my kernel log are repeated a couple of dozen time prior to the blank 
screen, but they mean nothing to me.  I am running on a new installation 
of 10.04 on a somewhat old Dell Dimension 2400.  I can see no pattern as 
to when the error(s) happen.

[drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed... GPU hung
render error detected, EIR: 0x00000000
[drm:i915_do_wait_request] *ERROR* i915_do_wait_request returns -5 
(awaiting 295143 at 295142)
[drm:i915_gem_idle] *ERROR* hardware wedged
[drm:i915_gem_entervt_ioctl] *ERROR* Reenabling wedged hardware, good luck
[drm:i915_hangcheck_elapsed] *ERROR* Hangcheck timer elapsed... GPU hung
render error detected, EIR: 0x00000000

Any assistance is greatly appreciated.
