All,

Pulled 2GB of RAM and the system still hangs after a few seconds of 
running the dd w/4GB RAM and amd64 generic on FreeBSD 5.3-REL.

Upgraded the kernel to:

$ uname -a
FreeBSD d10.bidx.com 5.4-PRERELEASE FreeBSD 5.4-PRERELEASE #0: Thu Mar 
31 13:55:10 EST 2005     root@d10.bidx.com:/usr/obj/usr/src/sys/GENERIC 
  amd64

... and got the exact same hang w/4GB of RAM and 5.4-PRE...

Can someone/anyone with a Tyan motherboard and 1 or 2 CPUs (I'm 
currently using the non-SMP GENERIC kernel even though I have dual 
Opteron 246's) try to reproduce this problem when running:

	dd if=/dev/mem of=/dev/null bs=1024k

Thanks,
Gary
