Boot hang due to "pipe: fold file_operations instances in one" in next-20130408
Subsystems (2)
Al,
I'm seeing a boot hang on Tegra in next-20130408. Even sysrq on the serial console doesn't work, yet I think cpuidle is still running since the LED that shows CPU power is flickering.
git bisect points at commit 9984d73 "pipe: fold file_operations instances in one". Reverting the-merge-of-the-branch-that-contains-this-patch from next-20130408 certainly solves the problem; reverting just that one patch is a bit painful since it's in the middle of a bunch of other cleanup.
Do you have any idea what might be wrong? I can't see anything obvious in the patch.

It's Ubuntu 12.04.01 for ARM (armhf), with quite a few updates not installed.
