| |
Recently the bogomips measurement has gone all haywire. Every once in a while when I boot up the bogomips measurement will be absurly high (i.e. 5 Terahertz), with obvious associated problems. This happens in recent kernels with both gcc-2.96-81 (redhat) and egcs-2.91.66. It does not happen with early 2.4 kernels or 2.2 kernels. It does not happen all the time. It never happens from a cold boot, and (almost) always happens in a warm reboot. In particular, MILO (which is a stripped-down linux 2.0 kernel that loads the real kernel) always measures the bogomips correctly immediately before loading a new kernel that measures it incorrectly.
The system is: Alpha LX164 (21164 chip) at 600MHz Kernels 2.4.7-2.4.9.
Cheers, -- Bob
