Are you certain that you are using the 3c59x driver for this device?
It appears that you are using a eepro100 driver, and it's likely not a
recent one.

For the eepro100 driver, this status means that you are receiving more
packets than the interrupt handler can process.  You should check what
other device is raising interrupts, or keeping interrupt blocked.  A
typical culprit is a SCSI driver.

Perhaps...

Definitely not.  You should leave autonegotiation on, and never force
full duplex.

Hmmmm, you should get your OS from a vendor that supports clusters.

Please don't force full duplex.  That leads to problems.

This is a misleading caused by an invalid modules.conf setup.
