   Timeouts are caused when the system doesn't receive the transmit complete
interrupt after the packet has been transmitted. This can be caused by the
interrupt that is set on the card not matching the kernel configuration or
can be caused by another card conflicting with the same interrupt. You may
wish to check the soft config and make sure that it is set for irq 5. You may
also wish to try a different interrupt (like irq10). If your machine is a PCI
machine, you may wish to check the BIOS to make sure that irq5 (or whatever
irq you decide to use) is properly allocated to the ISA bus. There are no
known bugs in the 'ed' driver and SMC Elite 16 cards are known to work fine
(have been specifically tested in the release).
