intel 82550 pro/100 ethernet 5.x timeouts

[Brett Krueger]

Hello people,
	I've been sifting through alot of lists lately and finally decided to 
make a post out of this since ive tested it on multiple systems without 
success.  p166, pII 400mhz, p4-3.0ghz HT.
specifically:

fxp0: <Intel 82550 Pro/100 Ethernet> port 0xa000-0xa03f mem 
0xf5000000-0xf501ffff,0xf5020000-0xf5020fff irq 22 at device 2.0 on pci2
miibus0: <MII bus> on fxp0
fxp0: Ethernet address: 00:02:b3:4c:b4:74

In this current machine, ive tested it on 5.4RC4, and 5.4RELEASE as with 
5.4STABLE. Though I have tried 5.3 as well.

The Error:

May 19 16:55:29 titan kernel: fxp0: DMA timeout
May 19 16:55:29 titan kernel: fxp0: SCB timeout: 0xff 0xff 0xff 0xffff
May 19 16:55:29 titan kernel: fxp0: DMA timeout
May 19 16:55:29 titan kernel: fxp0: SCB timeout: 0xff 0xff 0xff 0xffff

If anyone has a fix for this or found a workaround, id love to hear 
about it.  Sadly, our company has 15 of the damn things they purchased 
for a project that are now.... useless for freebsd dev.
Thank you for your time.
