When the pcnet card is running, an interrupt will be issued and at some point (e.g. after a certain receive interrupt) the value of the CSR0 register is set to 0x8000 (error), after which the incoming packets will not be received properly.
How do I handle such an error interrupt?

Are you sure that's the value of CSR0? According to the datasheets, that value isn't possible.
