Hi all,

I have a Dell PE2850 with 4 intel ethernet card. I cvsup the src yesterd=
ay.
em0 and em1 is 82541 which base on the mainboard. em2 and em3 is 82546EB=
  =

which plug in
PCI-X bus.
After I load the new kernel, kernel said: em2 watchdog timeout and could=
  =

not send any
packet out. I switch the line to the em0, it worked. After 5 min. em0  =

hangup too,
kernel said: em0: watchdog timeout.

There is `pciconf -lv | grep em` command print out.

em0@pci6:7:0:   class=3D0x020000 card=3D0x016d1028 chip=3D0x10768086 rev=
=3D0x05  =

Anyone know what is the problem?
