Is it related to this thread: http://lists.freebsd.org/pipermail/freebsd-stable/2010-February/054755.html I have been fighting other issues (mainly countless "Command WRITE(10) took X.XYZ seconds" in the VM's vmware.log file under moderate I/O) with VMware Workstation 7 on a Linux host with an AMD Phenom(tm) II X4 945 Processor, but I still have more testing to see if I can work through it. I also do not want to take over this thread. Sean -- scf@FreeBSD.org
