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 Vivek Khera wrote: > if you've got > 4GB ram, you pretty much *must* run something newer > than 5.3-REL.
