Can you please post your "cpuid" lines from your bochsrc file and
the CPU configuration related lines from the top of the bochsout.txt
file?
I don't have a bochsrc - I just run:
bochs -q 'floppya: 1_44=odin1440.img, status=inserted' 'romimage:
file=../seabios/out/bios.bin'
and then select option '6'. Below is the system config output:

Stanislav, you happen to know why WRMSR is not recognized here?
I was now able to reproduce it:

It happens because your Bochs 2.4.5 version was compiled without x86-64 support
and --enable-long-phy-address
and only supports 32-bit phys_bits. You can recompile it or upgrade to 2.4.6 to
fix this.
