Cellphone picture of call trace

Description of problem:

Just updated to the latest kernel version 4.1.4-200.fc22.x86_64, but this panics on boot after only 1.6 seconds. Can't find any log files using journalctl, maybe because it's too early in the boot process?

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

4.1.4-200.fc22.x86_64

How reproducible:

Just booting my system and selecting the most recently installed kernel version causes this panic. When using the previously installed version (4.1.3-201) it works just fine

Steps to Reproduce:
1.
2.
3.

Additional info:

Shuttle barebone, SZ77
Intel® Core™ i5-3570K CPU @ 3.40GHz × 4 
Gallium 0.4 on AMD OLAND

I took a picture of the screen, please see the attached file

Just let me know what more information you would need. Also, where do I find the relevant logs of the panic and the call trace? "journalctl -k -l -b -1" doesn't show anything useful.

This panic indicates it can't find the root file system. Can you try the 4.1.5 update in testing in bohdi and see if that works for you?

Comment 2 Diederik van Lierop 2015-08-15 06:57:53 UTC
Yes, 4.1.5 works again!

Thanks for looking into this.

Comment 3 Josh Boyer 2015-08-16 12:23:13 UTC
Thanks.  Typically that means that the initramfs wasn't created or loaded for some reason.  The new update likely didn't fix a kernel bug, but instead had the initramfs created properly.
