Dell Lat D420 cannot come out of suspend

[actionparsnip]

Never had an issue from Lucid and up. Now suspend leaves me with a blank screen.

I'd like to identify which kernel version introduced this regression. Can you test the following kernels and report back if they have this bug or not? You will need to install both the linux-image and linux-image-extra .deb packages.

v3.4 final: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.4-quantal/
v3.5-rc1: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.5-rc1-quantal/

Will do, gimma a bit :)

Sounds like this problem introduced in the RC7?

https://lkml.org/lkml/2012/7/15/104

And fixed upstream in:

 http://git.kernel.org/?p=linux/kernel/git/torvalds/linux.git;a=blobdiff;f=kernel/time/timekeeping.c;h=3447cfaf11e7d61b11d30bc063967e47d85e59d4;hp=269b1fe5f2ae2f7e6c0bb0fac8ce9a54e2d4d278;hb=3e997130bd2e8c6f5aaa49d6e3161d4d29b43ab0;hpb=33d519feaccb8a1208f736d00f53a2a73d98ffaa

3.5.0-5.5 (the RC7 rebase) hits this bug for me.

While up to and including 3.5.0-4.4 is unaffected.

[actionparsnip (andrew-woodhead666)]

Both:

v3.4 final: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.4-quantal/
v3.5-rc1: http://kernel.ubuntu.com/~kernel-ppa/mainline/v3.5-rc1-quantal/

Are fine. Suspend is good and video and wifi all come back :)

Thanks for the testing, actionparsnip.

Thanks for the info, Francis.

This bug should be resolved when we rebase to v3.5-rc8.
