[eepro100] VESA causes "eth0: card reports no resources" ?!?!

I remeber here a special thing from old days !!
As I used Windows-NT before, I had problems with the
serial line in connection with a modem (internet).
When I was surfing with netscape and I was scrolling
the view of the page, some errors occured on the PPP
I found in the internet, etc., solutions for the problem.
One was the activation of the FIFO of the 16550, and the
Switching of a special PCI Retry Freature of
the graphics controller. This was one checkbox in the
old NT 4.0. I do not remember the exactly name, but there
was a feature, which has boost up the graphic card's
priority on the PCI bus. The AGP is also organized as a further
PCI bus with a PCI bus number.
So I think, that there is a relation between your problem
An other point my be the IRQ load. The eepro100 driver
receives a packet, pulls the IRQ line. The IRQ service
routine fetches all received packtes since the last IRQ
call, and then fills up the receive buffer area, so that
eepro100 has space to write in the further received packtes.
If those area is used and NOT REFILLED, the eepro100 chip
sets the flag haeving NO RESOUCE !
So the bus load or interrupt load can be the reason for that.
