I checked the git log and the revert that fixed my problem with 3.0-rc2 is now included in 3.1-rc1, so it seems that something else is broken now. I tried to revert the revert, with the idea that maybe the hwmod changes were also included in 3.1-rc1, but it didn't help and I'm still getting a similar oops.
