Dell D620: Resume from suspend to ram fails

[Louai Al-Khanji]

My Dell Latitude D620 does not wake up from resume successfully. X comes back up but the hard drive does not work. No apps can be launched, reads/writes in already open apps fail. I will post kernel output in a moment.

This was present in hardy. I now tried the new Intrepid beta release, hoping that the newer kernel release might fix this, which was not the case. lspci and lsmod output below. I suspect the ata_piix driver but cannot prove anything. :) This used to work in older releases, I am not certain when it regressed.

Here is a snippet from the end of the kernel complaints. If more is needed I can provide more extensive error messages, although it is a bit laborous (what with no working disk to store the messages on).

Hi Louai,

The following wiki might help with gathering some additional debug info:

https://wiki.ubuntu.com/DebuggingKernelSuspend

However, the error message you posted indicates this may be a hw error:

Just curious what happens if you try to Hibernate instead of Suspend? Thanks.

Hibernating works fine. I also get these messages _only_ after suspend, never otherwise. I'll read through the wiki page soon.

Hi again,

the wiki material didn't seem relevant to my problem, since the system does come back up, just without a working hard drive. Is there anything else I can try? If not I'm going to start trying older (vanilla) kernels soon to find out at which point it broke, and maybe find a patch....

Care to attach your full dmesg output after coming back from suspend? If you are able to do a git bisect to narrow down a patch which introduced this regression that would be great. Thanks.

Hi Lauai,

Care to test the most recent pre-release of Jaunty - http://cdimage.ubuntu.com/releases/jaunty/alpha-2/ - and confirm if this is still an issue? You should be able to test suspend via a LiveCD. Please let us know your results. Thanks.

Hi Leann,

Sorry for the delay, I've been more busy lately than I would like... I just tested alpha-3 and the same bug is still present.
