Re: Lombard hard freeze (update: mem>64MB)

Well, if we're gonna do some controlled tests we
should all probably start out with the same kernel to
begin with. Which one is the latest greatest stable
version? I suppose we should all test with the exact
same kernel config, so if someone wants to put their
kernel, system.map, and modules up on an ftp site so
we can all start with that kernel, I could start
testing diff. configs on my PB immerdiately. :)

what kernel versions were these success stories
run on?

Yes, we have to gather more data. Than then we have
to seperate
the problems and search for similiarties and
differences in the
machines.

There seems to be a significant number of people
having this hard freeze
problem with Lombards. Here is my preliminary list,
if I counted
correctly:

	Hard Freezes occuring:

Tim Wojtulewicz		Pismo 	128 MB
Bernhard Reiter		Lombard 128,192   2.2.14,
2.2.15pre19
Gabriel Ricard	    	Lombard 192 MB   + other
problems
Mario Scarpa	        hard freeze as described?  64
MB + other problems


	Running fine:

jeramy b smith		lombard	192 MB
chris mccraw		lombard 128 MB 		2.2.12 thru
2.2.15pre20



As I have no idea on how to compare the stress
tests, I can only say
that in 95% of all my test cases I can trigger a
hard freeze within three
runs of:
	rpm -ba gnomehack.spec
(You can get my src.rpm from:
ftp://intevation.de/users/bernhard/)

There was one day, when I could run it five times
but still a hard
freeze later.


So we should gather more data on how to recreate the
bug and then
ask more people to try to trigger it. As you can see
from my preliminary
tests, there is no obvious pattern. Maybe we should
also check the
different lombard models, if there are any. (At
least I have a german
keyboard, e.g.)


Oh and more details from my part:
My RAM test from MacOS was completed fine, reporting
no errors.
Adding the mem=64M option to the bootup (I am using
bootx, could that
make a difference too?) seems to make the system
more stable so far.

Jeramy, Chris: can you tell us which kernel and
bootprocess you are using?
	Are you sure that linux uses all the memory?
	Can you build gnomehack three times?
