I'm using yaboot too. Does your kernel intialize the
video correctly when you first boot the machine up
from a cold state (as in, it was shutdown, not a
reboot)? I have to go into OF from a cold state, and
boot my macos partition just to the point where the
ROM initializes the video with a grey screen,
otherwise, I get this odd lockup when I boot into
Linux. As the kernel messages scroll down the screen
its fine until it has to scroll the screen up, it just
locks up when it does that. What kernel, yaboot, and
LinuxPPC (or other distro) version are you using?

  I'd be happy to run some tests if needed.  My
network access on the
lombard is a bit unstable right now so I couldn't
download the gnomehack
source...  I should be back to normal in a few days.
 I don't even have
gnome installed anyway...

Yes, we have to gather more data. Than then we

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

	Hard Freezes occuring:

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

	Running fine:

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


As I have no idea on how to compare the stress
tests, I can only say
quoted
that in 95% of all my test cases I can trigger a
hard freeze within three
quoted
runs of:
	rpm -ba gnomehack.spec
(You can get my src.rpm from:
ftp://intevation.de/users/bernhard/)
quoted
There was one day, when I could run it five times
but still a hard
quoted
freeze later.


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


Oh and more details from my part:
My RAM test from MacOS was completed fine,
reporting no errors.
quoted
Adding the mem=64M option to the bootup (I am
using bootx, could that
quoted
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?

Yes, my Pismo will initialize the video correctly from a cold boot.
I'm using yaboot with kernel 2.2.15-pre19 I believe.

  The video initializes fine no matter how I boot into linux.  I'm running
kernel 2.2.15pre20 rsynced from linuxcare.com.au on Linuxppc2000.
Currently booting through yaboot 0.5.  I've posted my current kernel,
System.map, and modules folder on my website at:
  http://www.seanano.org/linux/ppc
Be warned however, that this is not a gerneric kernel.  I don't have a lot
of options enabled.  There is no ppp support, only bmac ethernet driver,
only MESH for scsi, so in other words, I wouldn't use this kernel except
for the lombard.
