That didn't work, and I eventually found a way around it. On one laptop I tried to install FreeBSD on, it wouldn't even boot without SpeedStep turned off - it crashed immediately after trying to boot the kernel. On another, it would panic when starting to install packages from the CDROM, with '_mtx_lock_flags_'. Turning off SpeedStep and thus throttling the CPU to 60% allowed the install to continue far enough to get a minimum system installed, but it still paniced if I tried to install the ports distribution. After installation, I never again saw the panic, even when running sysinstall again to install the remaining distributions. -- Bruce Cran
