I have been running Linux successfully for several months on
an IBM Thinkpad 510Cs and have noticed something odd -
whenever I boot into Linux 'cold', I get 5.11 BogoMips,
but when I boot first to DOS, then Ctl-Alt-Del and reboot
to Linux, I get 14.33 BogoMips. Perhaps DOS is enabling
a CPU cache that Linux doesn't know about? Has anybody
else experienced this? If my theory is vaguely correct, is
there a kernel patch available to fix this?
