Ein Pentium I 100 MHz sollte ca. 40 BogoMIPS ausweisen.
Hier wird beim Start 196 BogoMIPS gemeldet.
Lt. Mini-HowTo kann eine falsche Konfiguration dafür verantwortlich sein, aber wo?
IIRC wurde der Bogmips-Code irgendwann in den 2.2.x Kerneln geändert, so dass jetzt die Zahl doppelt so hoch ist.
Nein. Auszug aus BogoMIPS FAQ: No, the BogoMips algorithm, contrarily to popular believe, did NOT change over the various kernel versions. What did change in kernel version 2.2.13 is the CPU state setting just before the BogoMips calculation. This affects the BogoMips rating for all Intel and AMD Pentium variations, resulting in approximately 2*clock, where these were not 2*clock. Zum Problem des Pentium I 100 (eine Moeglichkeit... :-) If a kernel is not compiled specifically for the pertaining CPU, also some (even large) variations of the BogoMips ratings can occur, mainly due to erroneous alignment. This problem apparently only occurs on the various x86 CPUs (Intel and clones). Fortunately it can easily be solved: recompile the kernel specifically for your CPU.
