00:14.0 Ethernet controller: Digital Equipment Corporation DECchip 21041 
[Tulip Pass 3] (rev 11)

Above is the lspci output for my PCI Ethernet card.  Below is what happens 
when I try to boot 2.6.0-test9.  2.4.x kernels have been working well on the 
same card for a long time, so the hardware seems basically OK.

Configuring network interfaces... eth0: set link BNC
 eth0:    mode 0x7ffc0040, sia 0x10c4,0xffffef09,0xfffff7fd,0xffff0006
 eth0:    set mode 0x7ffc0000, set sia 0xef09,0xf7fd,0x6
 eth0: timeout expired stopping DMA
