em(4) - memory access and bus master bits were not set

Hi all,

I am using em(4) on a VMware ESX - FreeBSD 7.0-STABLE VM.

My em0 interface will consistently go down when it is hit with a reasonable amount
of I/O.  Upon bootstrap dmesg(8) reports:

   "em0 memory access and or bus master bits were not set"

I suspect this is the likely cause (bug) of my problem. This has been discussed
and supposedly fixed:
 [http://unix.derkeiler.com/Mailing-Lists/FreeBSD/net/2007-07/msg00262.html]

I am enabling em(4) via the following *.vmx tweak as recomened by Ivan
(http://ivoras.sharanet.org/freebsd/vmware.html):

   ethernet0.virtualDev="e1000"

I am having to revert back to the crusty lnc driver - le(4).

Can anyone suggest how to make em(4) play ball in a -STABLE ESX VM ?
