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.
