I have noticed with all users running Hedwig that some network cards based off the Tulip driver (most notably LinkSys EtherFast cards) do not function. This is characterized by a lack of network card initialization at startup, followed by an inability to open eth0 (and the message "Delayed eth0 initialization"). In addition to that, issuing "insmod tulip" returns only that the device is busy and does not elaborate. Both the standard tulip.c within the kernel and the LinkSys-provided tulip.c have been tested, and both have returned the same results. The only conclusion that I can arrive at is that Hedwig contains some sort of bug which interferes with the operation of Tulip-based cards; it is also notable that such activity is not present in Apollo.
By the way, I forgot to mention that I have been reading reports of similar happenings on LinkSys mailing lists and the like, if that helps any.
This appears to be the same issue as #2744, so I'm duplicating there. *** This bug has been marked as a duplicate of 2744 ***
