Revision d18bbc215f81710e1eab7120becafa910554d68d authored by Andrew Morton on 02 July 2014, 22:22:38 UTC, committed by Linus Torvalds on 03 July 2014, 16:21:54 UTC
Revert commit 939f04bec1a4 ("printk: enable interrupts before calling console_trylock_for_printk()"). Andreas reported: : None of the post 3.15 kernel boot for me. They all hang at the GRUB : screen telling me it loaded and started the kernel, but the kernel : itself stops before it prints anything (or even replaces the GRUB : background graphics). 939f04bec1a4 is modest latency reduction. Revert it until we understand the reason for these failures.
