Bug#277081: kernel-image-2.6.x-n-x86 fails to compute correct CPU speed 4 out of 5 boots, and USB fails
Horms,
The problem appears to be fixed in 2.6.8, in that behaviour is the
same as 2.4.x kernel -- wrong bogomips calculated, but USB
and internal PS/2 mouse work anyway. (My original report omitted
to say that internal PS/2 mouse didn't work if speed was
incorrect in 2.6.7 kernel.)
Thanks for your time,
Bill Dudley
