[Bug 119940] Re: /proc/cpuinfo reports incorrect information for Via C3
Unfortunately, Ubuntu no longer even supports booting from this nice
little CPU beyond lucid. Obviously, this will not get fixed in Ubuntu.
Marking as such.

Bug description:
Binary package hint: linux-source-2.6.15
The output of "cat /proc/cpuinfo" is wrong
processor : 0
vendor_id : CentaurHauls
cpu family : 6
model : 6
model name : VIA Samuel
stepping : 2
cpu MHz : 400.179
[...]
My CPU has 600 MHz. And while cpu frequency scaling was still working
(c.f. bug 45747) I always saw the true frequency to be underreported
by 33%. It was 400/200 MHz when the machine was really running at
600/400 MHz.
Some possibly related issues where frequency is incorrectly reported
are being discussed at
