On my main workstation, kfreebsd 8.2-1.1 and later versions CPU-faults early on boot. This affects the i686 version only (not amd64 one). 8.2-1 is not affected.
Probably related to: * Build by GCC 4.6. (Closes: #594288) Would you mind to rebuild latest kfreebsd-8 with gcc-4.3 from stable ? And by current "gcc-4.6 -fno-gcse" ? Petr
