suspend/resume is currently broken on imx51

[Paul Larson]

Since the update of the fec driver in the imx51 kernel, suspend/resume is known to not be working.

[Paul Larson (pwlars)]

This had been previously discussed in bug #559065, this bug is splitting the suspend/resume issue out.

[Bryan Wu (cooloney)]

I got a patch from upstream to fix this suspend/resume issue. Could you please help me test it:

kernel package:
http://people.canonical.com/~roc/kernel/lp571192_suspend/

Patch:
http://kernel.ubuntu.com/git?p=roc/ubuntu-lucid.git;a=commitdiff;h=5d1c0e3c5058d39854deb2b09a69f9b640ce276d

Thanks a lot,

Still fails to resume. No log output to debug with.

[Bryan Wu (cooloney)]

Tobin,

Could you please help to test this again on Babbage?

Lee Jones just fixed a suspend/resume bug in his T61 which is related to SD/MMC. So please try this on Babbage:
--
echo "SUSPEND_MODULES=\"sdhci sdhci_pci\"" | sudo tee -a /etc/pm/config.d/suspend_modules
--

And try suspend/resume. to see whether it works or not.

Thanks a lot,
-Bryan

[Tobin Davis (gruemaster)]

No, this doesn't appear to help matters.

Tested suspend on Babbage board C with 2.6.31-608-imx51. One of the power LEDs stays on and cannot resume.

Attached /var/log/pm-suspend.log

[Bryan Wu (cooloney)]

Hans,

Thanks a lot. It looks like it suspend successfully, but cannot resume.

Could you try upstream kernel 2.6.36+rc3?

-Bryan

[Hans Crijns (hanscrijns)]

Bryan,

Would love to try, but I can't find imx51 version online and have never
cross-compiled before.

Do you have the kernel lying around or some clues on what to do?

Thanks,

Hans

package not in natty

[Tobin Davis (gruemaster)]

This is still a valid issue, however, support for this system ended November 2011 (18 month support). Closing as "Won't Fix".
