After compiling my own kernels from 2.6.11 to 2.6.14, I found that
only the Ubuntu official kernel didn't lock up hard after 2 hours or
so. Why? Because it didn't provide the frequency scaling driver
longhaul.ko for my VIA C3 CPU. WIthout longhaul frequency scaling, my
laptop is rock stable.
According to http://tinyurl.com/k7wlw , this has been going on since kernel 2.4!
In http://tinyurl.com/oxetd Dave Jones says,
Version 2 of longhaul is the same as v1, but adds voltage scaling.
12 * Present in Samuel 2 (steppings 1-7 only) (C5B), and Ezra (C5C)
Output of cat /proc/cpuinfo included.
Output of dmesg also included.
As you can see, dmesg says the kernel detected a Ezra C5C version of
VIA C3. However, it also goes on to say, only longhaul v1 supported.
What's with that? Does that have anything to do with the laptop
locking?
When the laptop locks, nothing on the screen moves. I can adjust
screen brightness even in the bios, but once it locks, I cannot do
that. Numlock,Capslock,Scrolllock do not change when I press their
buttons either, and pinging my lockedup laptop does not solicit a
reply.
So, it is unfortunate, but I don't think any kernel dumps or panic
messages were output. I should know. I've been experiencing this for a
year or so.
Please, somebody fix this frequency scaling issue!

2.4 never officially had cpufreq.

v2 is v1+voltage scaling. As the driver doesn't do voltage scaling,
there's no difference.

No. It's to do with the way frequency scaling is implemented on those CPUs.
It's very tempremental. If there's any (for eg) IDE DMA that occurs
during a frequency transition, everything goes bang a short time later.
There's an ugly patch below that was submitted, which fixes it for
some people, but as it's a) ide specific, and b) completely the
wrong place to do this and c) racy, I never merged it to mainline.
I'm hopeful that future generations of their CPUs will behave
in the same manner of other implementations that other x86 vendors
have invented, where we don't need such hacks.
> Please, somebody fix this frequency scaling issue!
I'm actually contemplating marking it CONFIG_BROKEN in mainline,
as there's not a great deal we can do to make it work without
significant infrastructure to quiesce DMA.

If I understand the documentation correctly you simply need to disable
the master bit on the root bridge during the transition and the PCI
transactions will be stalled, providing you don't take too long about
it.

tried it, didn't change anything.
The current code goes one step further, and disables it for all devices.
Still no joy. See the do_powersaver() function in arch/i386/kernel/cpu/cpufreq/longhaul.c

Good idea! Too many people fall foul of this (well, I did...).
