hardware info

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


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:


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
Comment 4 Dinesh Joshi 2012-02-20 09:44:25 UTC
This bug doesn't seem to exist on the latest upstream. I am using the Ubuntu precompiled mainline kernel.
