I only have an 8139C and I've not ever seen an error of any kind on it,
hence my comment about work may be required if any error conditions happen.
Someone else asked me a similar question some months ago, and I suggested
putting in debugging prints in the driver wherever an error is detected.
That way you will see something if the card causes any problem and then
reboots the machine.

There may also be problems with the P4 processor, we don't have any here
to run on.
