v2.6.28-omap1 tagged, some bugs remain

Hi all,

I've just tagged v2.6.28-omap1, and looks like we might want to also do v2.6.28-omap2 as there are few annoying bugs remaining:

- According to Jarkko Nikula, ASoC does not currently work because of some recent clock changes.

- MMC seems to be broken for omap1, Ladislav Michl might have a patch coming up for that.

- I2C is broken for 2430 according to Kainan Cha.

Also looks like source.mvista.com is down, so please use the kernel.org tree.

Regards,

Tony

Confirmed on omap3evm.

Thanks, can you try to git-bisect the breaking commit?

And also musb might require some patches, pending comments from Felipe.

I did very short test on sunday and it was working at least when checkouting into 12081fce83c10221ccd1b282e3e2fbe56f742e21, i.e. commit before 60b8b431e47d8c5b8c02a2e4fa9af388aae20790 which was mentioned in the commit 818862e11bad091dc635baedace58265a126b5c8 :-)

Paul was going to take a look tomorrow.

Jarkko

I tried ASoC by removing the commit "ARM: OMAP3: Mask interrupts when disabling interrupts" (023ae898bbbed8c2bc4d38bfbd05d2fee91c3468) and audio worked fine for me.

Just to verify -- does this issue manifest as a segmentation fault?

Here's what I am seeing on Overo with the current top of tree:
