hardware info

Please note although I am using Ubuntu, I am running the stock mainline kernel from Ubuntu's kernel ppa.

Description:

On this hardware, when I attempt to suspend to ram, once in a while it leads to a kernel panic.

Steps to Reproduce:

Followed the debugging steps here:
https://wiki.ubuntu.com/DebuggingKernelSuspendHibernateResume

First:

1. setfont /usr/share/consolefonts/Uni1-VGA8.psf.gz
2. sudo pm-suspend

Then repeated pm-suspend, wakeup cycle at the command line until I got the kernel panic.

Additional info:

I am attaching hwinfo output and screenshots of the actual panic.

Note: I have a sucky iPhone cam and the font on my screen was tiny so I need to attach several pictures.

It's great that the kernel bugzilla is back.

Can you please verify if the problem still exists in the latest upstream
kernel?

This bug doesn't seem to exist on the latest upstream. I am using the Ubuntu precompiled mainline kernel.

Thanks.
