Got one step forward with the hard freeze problem.
My local Apple shop (ProDatenTechnik in Osnabrück),
was to kind to let me check through a new memory module.
When I had only 64MB the system was stable!
I managed to compile GRASS (which is among the biggest free software
projects) and other things.
Plugging in a different 128MB and a different 64MB, both in the first
slot, made the system unstable each time.
This explains why Micheal has a stable system.
Sadly it is still a big problem.
To answer some of the suggestions:
The problem is there, even when I never start X11 and work
from the virtual console. There is absolutly no output.
No ethernet network ping, no memory monitor, no kernel panic, nothing.
The cursor stops blinking (and everything else moving) and it is over.
As about the power consumption and the heat: It is my understanding that
the fan should start up when there is too much heat controlled by
hardware. But the fan does not start. And freezes also occur when the
machine itself it cold. I also do not quite understand how the power
consumption could be a problem here.
It would so nice to have a person who can debug it.
I will test two things:
Setting mem=64M and see if it makes it stable.
Maybe a development line kernel has some fixes for this stuff,
I shall try one.
Maybe we should ask for Lombard users which have a stable system
with more as 64MB memory. Can they do huge compiles?
Somebody should have a lombard the symptom and the guts to debug it.

ps.: Please remember that I am not on the dev list.

I've been paying attention to this thread for a while since I have a
Pismo and mine is exhibiting the same problems that yours is. I have
128M of RAM in mine (one stick). This is memory straight from Apple.
I also see kernel panics/lockups during large compiles. I managed to
make it through KDevelop 1.2, but it will ALWAYS die during XFree 4.0.

So it worked with your original 64 megs, but it fails with a different 64
meg part and a 128 meg part? I don't see how that can be anything but bad
hardware, either something wrong with the motherboard or a pair of bad
SIMM/DIMM parts or dirty contacts or incorrectly seated RAM.
Had the strangest thing the other day... 8100 clone wouldn't boot up. I
figured the PRAM battery was dead, so bought a new one and swapped it, no
luck. Started pulling nubus cards, etc. Had it all down to the mobo and
nothing. Yanked the RAM and it came back up. Reseated the RAM, and it
has been fine since. :-/ Weird....

consumption could be a problem here.
Me either. I think the fan is started automagically in hardware anyway.
At least I'm pretty sure it was on the wallstreet....

A brief Haiku:
Microsoft is bad.
It seems secure at first glance.
Then you read your mail.

Send me a memory module :-)
Does this mean I was lucky to get only 64 MB, or to get a working 64MB
module?
How much RAM does Paul have in his Lombard?

It's supposed to start automagically. I've never noticed that happen
though. Maybe this summer :-)
