Kernel hangs....

[Zach Pfeffer (pfefferz)]

I see this on the latest 11.09 build.

[Jassi Brar (jassisinghbrar)]

The low-level debugging over a serial port is know to be not very robust, esp when the platform has to do some initialization of the ports before serial drivers are loaded.

[warmcat (andy-warmcat)]

I added Jassi's config patch to tilt-linaro-android-3.0, please give it a try.

[Zach Pfeffer (pfefferz)]

Just to be sure, did this get pushed out to:

git://git.linaro.org/people/andygreen/repo-branch-archive.git
tilt-linaro-android-3.0

?

[warmcat (andy-warmcat)]

Yeah, you can confirm yourself with gitweb easily enough. here's the 'permalink' for that branch

http://git.linaro.org/gitweb?p=people/andygreen/repo-branch-archive.git;a=shortlog;h=refs/heads/tilt-linaro-android-3.0-29e982052f8a8050ea76d0946b79e57e365e460a

...you can see Jassi's patch is the HEAD. In this case the patch is android-specific so it went on at the end of everything.
