* Boot hang due to "pipe: fold file_operations instances in one" in next-20130408 @ 2013-04-08 21:19 Stephen Warren 2013-04-08 21:22 ` Al Viro 0 siblings, 1 reply; 3+ messages in thread From: Stephen Warren @ 2013-04-08 21:19 UTC (permalink / raw) To: Al Viro Cc: linux-next-u79uwXL29TY76Z2rM5mHXA, linux-tegra-u79uwXL29TY76Z2rM5mHXA 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. ^ permalink raw reply [flat|nested] 3+ messages in thread
