[Bug 229580] Re: P3: Hardy 64-bit kernel locks up on Phenom based system

[Leann Ogasawara]

Hi Peter,

I'm assigning this to the kernel team for now.  I'll get in touch with
them immediately to see who will specifically be assigned.

Just to add more info for the kernel team I also came across the
following LKML thread http://lkml.org/lkml/2008/3/8/128 which I assume
was also started from your customer?  (See also
https://bugs.launchpad.net/ubuntu/+source/linux-meta/+bug/197252).
There were comments there about using the kernel boot option
nmi_watchdog=1 as a workaround.  However, in the end it seemed like a
BIOS update coupled with a newer kernel resolved the issue.  So it seems
the BIOS update, which the customer already has, and the Hardy kernel is
still problematic.

I also quickly glanced at the debian bug report you reference.  The
stack trace there is not really the same as what the customer is seeing.
However, the reporter(s) there mention the issue they were seeing was
resolved with the usptream 2.6.25 kernel.  The kernel team has the
Intrepid Ibex kernel available for testing.  It has been rebased with
the upstream 2.6.25 kernel already so it probably won't hurt for you (or
the customer) to test it to see if it also helps in the meantime.  It is
currently available in the following PPA:

https://edge.launchpad.net/~kernel-ppa/+archive

If the customer isn't familiar with how to install packages from a PPA,
just tell them to do the following:

Create the file /etc/apt/sources.list.d/kernel-ppa.list to include the
following two lines:

deb http://ppa.launchpad.net/kernel-ppa/ubuntu hardy main
deb-src http://ppa.launchpad.net/kernel-ppa/ubuntu hardy main

Then run the command:

sudo apt-get update

They should then be able to install the linux-image-2.6.25 kernel
package. After they've finished testing they can remove the kernel-
ppa.list file and run 'sudo apt-get update' once more.

Hope this helps for now.  Thanks.
