Description of problem:
When booting with kernel-4.5.2-301.fc24.x86_64, I get an 

Version-Release number of selected component (if applicable):


How reproducible:
It seemed to work this morning, but I had a hard freeze this afternoon and then subsequently all attempts to boot to this kernel have been met with this panic. Booting to the kernel-4.5.1-300.fc24.x86_64 kernel works just fine.

Steps to Reproduce:
1. Boot the kernel
2.
3.

Actual results:
Panic

Expected results:
System should boot.

Additional info:
See attached photo of the panic.

Very strange that it worked and stopped, and there was nothing between 4.5.1 and 4.5.2 that jumps out as likely to change this path.  Possible that there was a memory failure that this particular build is now hitting?  Curious if you can boot the rawhide kernel as well.

Comment 2 Stephen Gallagher 2016-05-03 19:15:53 UTC
Sorry for the delay; I hadn't had time to look into this until today. So, the kernel-4.5.2-301.fc24.x86_64 and kernel-4.5.2-302.fc24 kernels both fail to boot on this hardware. I pulled down kernel-4.6.0-0.rc6.git0.1.fc25 from Rawhide today and that appears to work just fine, so whatever is going on seems confined to the 4.5.2 kernel.

Comment 3 Josh Boyer 2016-05-26 19:23:38 UTC
I'm going to close this out.  If 4.5.5 still panics, please let us know.
