grub.cfg (note outb lines)

Description of problem:
Failure to boot.

Version-Release number of selected component (if applicable):
kernel-3.17.1-303.fc21

How reproducible:
Every boot.


Steps to Reproduce:
1. Upgrade and reboot


Actual results:
Right after choosing this kernel in grub, even with rhgb quiet deleted, screen is black - no scrolling text at all. Laptop gets hot, fans come on full, I have to force poweroff.


Expected results:

Boot

Additional info:
No recent (3.15, 3.16, 3.17 series) prior kernel behaves this way. I can boot find with kernel-3.17.1-303.fc21. Since the screen is totally black I have no indication what the problem is.

I do have a unique grub.cfg boot entry to disable radeon graphics so that I'm only using i915 graphics on this machine, so I'll include that grub.cfg. But no prior kernel behaves like this with the same grub.cfg add-ons.

Booted with kernel -303 and used journalctl -b-1 -k to extract the "dmesg" from the apparently successful previous boot, even though the screen was black.

*sigh* User confusion please ignore comment 1 entirely.

journal -303

Regressed to booting kernel -302 and used journalctl -b-1 -k to extract the "dmesg" from the apparently successful previous boot using kernel -303, even though the screen was black.

journal -303 debug

The 303 debug kernel does NOT exhibit the problem, this is journalctl -b -k booting this kernel.

Comment 5 Chris Murphy 2014-10-25 03:14:31 UTC
OK after several more boots of 303 nondebug, and each one black screening, I decided to download 3.17.1-303.fc21 rpms from koji and dnf reinstall *rpm; after that the problem does not reproduce. So it seems like it was a bad kernel install - pretty weird.
