Description Robert Hancock 2014-04-24 04:35:38 UTC
Description of problem:
On some systems, 3.14-based kernels appear to lock up immediately after boot. Using "earlyprintk=efi" (assuming an EFI system) shows that the kernel is panicing in acpi_tb_parse_root_table.

Version-Release number of selected component (if applicable):
kernel-3.14.1-200.fc20.x86_64

How reproducible:
Every time

Steps to Reproduce:
1. Boot 3.14.1 on affected system
2.
3.

Actual results:
Kernel panics immediately on boot

Expected results:
System boots

Additional info:
According to the kernel bugzilla (linked) a patch is available to fix this problem though I have not tested it yet. It appears that systems with an AMI BIOS (as with mine) are affected. The patch is supposed to get queued for stable but has not been merged yet. This likely needs to be applied, as otherwise this will cause a major regression on a significant number of systems if the 3.14 update hits stable.

Comment 1 Robert Hancock 2014-04-24 04:44:27 UTC
Using the "acpi=rsdt" boot option works around the issue.

Comment 2 Josh Boyer 2014-04-24 12:45:18 UTC
Thanks for the pointer to the upstream bug.  I've grabbed the kernel patch mentioned there and included in in the scratch build below.  Could you try that when it completes and let me know if it resolves your issue?

Comment 3 Robert Hancock 2014-04-25 01:26:48 UTC
Yes, this build boots normally on my system.

Comment 4 Josh Boyer 2014-04-25 12:21:57 UTC
Thanks.  I added the patch to our tree.  It will be in the next build.
