This looks like one of the problems we're trying to solve in Ubuntu.

The wlan driver module needs to be unloaded on suspend and then
reloaded on resume

Is this with the ath6kl dirver module loaded ?

Do an lsmod before you try the suspend.

Suspend works on the 11.12 final RC:

[Zach Pfeffer (pfefferz)]

Looks like we're broken again on:

https://android-build.linaro.org/builds/~linaro-android/staging-origen-12.01-release/#build=2

Clicking the mouse or the keyboard doesn't wake the unit up.

[Zach Pfeffer (pfefferz)]

I see https://android-build.linaro.org/builds/~linaro-android/origen-ics-gcc46-samsunglt-stable-blob-12.02-release/#build=1 suspend and refuse to power back on after pressing various keys.

Would you please report the behavior when you plug-in/out a USB device
after pressing some key to resume?

Suspend -> Press a key to resume -> Plug-in/out a USB device

[Chengjie HE (chengjie-he)]

the suspend->resume, now is OK, the reason is too many irqs for uart makes the cpu stale;
new issue is suspend->resume->suspend, still struggling on this tough one

[Inderpal Singh (ips)]

The (suspend-> resume -> Immediate supend) issue can be fixed with the attached patch.
With this patch the system resumes fine but screen does not get updated. The remaining system works fine.

If I use software rendering there is no issue in screen updation after resume. Everything works just fine.
Hence, hardware rendering (Mali binaries in vendor.tar.bz2) has some issues with respect to suspend/resume.

[Inderpal Singh (ips)]

It is fixed. There was no issue as such with Mali binaries. The only thing was that Mali Power Management was not enabled in the kernel. Once enabled suspend/resume works fine even with hardware rendering. The screen does not freeze.

Summary: The following 3 things need to be done to fix the whole issue.

1. Disbale Kernel Low level debugging (CONFIG_DEBUG_LL)
2. Enable Mali Power Management (CONFIG_USING_PMM)
3. Use the patch attached in msg#17

I have tested this fix with kernel at [1].
Jacky, can you please confirm that it fixes the issue.

[Chengjie HE (chengjie-he)]

with the kernel patches and device/linaro/origen patch, this issue is fixed.
