linux-linaro 11.07 omap3 kernels have broken USB/Ethernet on Beagle xM rev C boards

Jassi: Do you have any rough idea (or suggestions of who to ask) for which patch included in 3.1-rc1 might have helped this out?

It would be good to pull it into the linux-linaro and linaro-android kernels.

thanks

Jassi replied privately that the likely candidate was:
   5fe8b4c19dc24e3bb873daf9e96a2439a83bbd79 'OMAP3: beagle: add support for beagleboard xM revision C'

I've now cherry picked that into my tree for 11.08

Nico, you might want to grab the commit id in comment #3 for the linaro-linux tree to resolve this bug.

as a (perhaps slightly useless) reference point, my beagle Xm USB ethernet works fine with the 11.08 RC (Rev A2 however)

Yeah, seems patch 5fe8b4c19dc24e3bb873daf9e96a2439a83bbd79 is the correct one to fix this issue. This was included upstream at at 3.1-rc1.

Nicolas, do you think you can cherry-pick this patch into Linux-linaro 3? This makes beagleboard xM rev C to boot with Linaro kernel.

Sorry, seems this patch is already applied at linux-linaro 11.08, so in theory we should be fine.

Now we just need to check the sauce that was applied at the package side.

Yeah, the issue affects rev C only (not A or B).

I tested hwpack: hwpack_linaro-omap3-x11-base_20110823-0_armel_supported.tar.gz
with rootfs: linaro-n-ubuntu-desktop-tar-20110823-3.tar.gz and
these problems appear to be fixed. The kernel version is: Linux version 3.0.0-1004-linaro-omap

Actually, it looks like I spoke too soon.

The USB keyboard became intermittent with these error messages:

The USB mouse continues to work.

Grrr, it looks like my USB keyboard has failed. This bug is probably fixed.
