Try without the ethernet card and switch IDE DMA off and tell me if it is
stable, there could be some cache coherency issues with some of the chipsets
used on these machines.
Another thing you can try is in set_context(), add an isync on the line
that contain the label "3:" as the doc states a context synchronizing
instruction should also be used for data sync. before mtsrin.
