Thanks!
This problem sounds like a bug in the longhaul driver though, which I
don't really know anything about. (The system should never crash,
regardless of what speedfreqd does.)
I've cc:d the cpufreq list to see if someone there can help. Dave?

Yeah, longhaul is badly broken right now, and tbh, I've no idea
what on earth is wrong. Speed transitions happen, and work correctly.
Then a few minutes later, system locks up.
I've been trying all sorts of things, from disabling PCI mastering,
disabling CPU caches, etc, but nothing seems to help. I'm truly puzzled.

I remember old versions of the C3 used to forget to snoop DMA traffic
while in the hlt instruction, so it wouldn't surprise me if there's some
other bug like that related to longhaul.
Do you mean that it will crash some minutes after a single transition,
or is it less deterministic than that? Do lots of transitions make it
worse? Is the delay between transition and crash a random or
approximately fixed length, and does it depend on either core or bus
speed?
The reason I ask is that I have the ear of Via engineering support at
the moment (we're using embedded C3's in a product at work), so I could
ask a few well-placed questions.

That's why I was hoping disablign mastering would do the trick.

Usually takes a few. I've noticed if I run cpuspeed, it steps it down
from 1.2GHz to 500MHz through a half dozen or so steps. Whilst it does
this, its stable. If I then kill cpuspeed, its stable.
But, if I leave cpuspeed run, and then do something CPU intensive, it
tries to jump up to fullspeed quickly (through less steps than
it took to scale down), when it does this, it hangs shortly afterwards.
We're not doing voltage scaling in longhaul yet, but that shouldn't
matter, as we should be booting at max voltage (as we boot at max speed)

I speak with the centaur folks regularly, but they haven't got any
ideas what the problem could be either.

Sebastian is reporting the problem with speedfreqd, which will use the
same number of steps both ways (and, depending on the CPU load curve, at
the same rate).
Does rate-limiting the transitions help stability?

Is voltage switching complex? It might be worth trying - its not
something which normally improves stability, but maybe there's some
regulator issue under load changes, or something...

With longhaul, its a little more complicated than it is with powernow,
as theres no bios table telling us which voltage should be used
for each frequency, and they vary depending on stepping & speed of the part.
The first version of the longhaul driver did actually do voltage scaling,
but the 'match the voltage to the speed' code was very crude, and
assumed that the voltage table was 1:1 with the frequency, which
worked for the most part, but was far from being 'the right thing'.
I'm not convinced that adding it back in would fix the stability problems.
If anything, it would add another variable.

Dear Jeremy, dear Dave, dear list,
I tried to collect more information using cpufreq.debug={1,2,3,4}. But I
don't see anything helpful in the output. Maybe you can find somehing,
so I'm going to attach it anyway. Would it be interesting to see if a
previous kernel version like 2.6.5 worked? I sure could install an
earlier kernel if you like. Maybe this has not so much to do with the
cpufreq-longhaul driver but with changes to the IO-section of the kernel?
A few days ago I converted all partitions on the computer from reiserfs
to xfs, but as you can see, this didn't change anything regarding the
freezes :)
Regards
Sebastian
P.S.: I hope you don't mind me attaching the various output as a
.bz-file. Unpacked it's ~24kB, bzipped only ~3kB.
Thanks
Sebastian
