>Description:

When stuff happens (like: using the disk for compiling, but also when
just opening webpages), the fxp0 will start giving device timeouts,
resulting in temporary loss of network connectivity.
With the 82550 fxp card in the machine the network outage will last some
2 seconds. 

With the following card:

  fxp0: <Intel 82558 Pro/100 Ethernet> port 0xe000-0xe01f mem 
	0xe3000000-0xe30fffff,0xe3101000-0xe3101fff irq 5 at device 17.0 on pci0
  miibus1: <MII bus> on fxp0

the timeouts would last 30 seconds or more.

This machine was running -current until some 3 weeks ago. It was
completely reinstalled with -stable. The cards worked without a problem
before that, so hardware problems don't seem to be very likely
