Thomas Moestl ported the gem driver, I don't know much about it. Most
likely the hardware violates the PCI spec in some way shape or form.

If it doesn't actually affect the interface just ignore it. There
was a recent commit to the gem driver to fix a problem which sounds
related:
tmm 2002/05/24 05:47:42 PDT
Modified files:
sys/dev/gem if_gem.c
Log:
Fully reset a gem on some error conditions; otherwise it would hang in
about 1 of 10 cases.
Proposed and tested by: phk
Revision Changes Path
1.5 +4 -0 src/sys/dev/gem/if_gem.c
Note that the hme driver gets errors back from the hardware quite often;
our best guess is that the hardware times out trying to push the on card
buffer out to main memory, either due to other bus traffic or due to the
latency timer being set too low.
