Output of lshw

Description of problem:
 I have several problems with kernel 4.12.5-300.fc26.x86_64.
 In particular, kvm-intel does not work and the module for a webcam causes a BUG

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

Version 4.11.8 is fine.

How reproducible:
The computer is an old HP with a core2 cpu.
I have just reinstalled fedora 26 from scratch; the installation kernel works
fine; I have found some problems with 4.12.5-300.
In particular
a) kvm-intel cannot be loaded with "input/output error"
b) executing cheese causes a bug warning

I have reinstalled the system from scratch since I had a serious corruption on the root (which is a btrfs filesystem). I do not know if this might be a different aspect of the same issue or unrelated.

Steps to Reproduce:
1. boot the machine
2. execute sudo modprobe kvm-intel
3. execute cheese

Actual results:
 kvm-intel is not loaded
 cheese freezes and in dmesg there is a BUG notification

Expected results:
 everything works

Additional info:

Trace caused by cheese

Comment 3 Luca Giuzzi 2017-08-22 19:22:02 UTC
I have checked the RAM with memtest+ and it appears to be sane.
This bug, for what concers v4l, is a duplicate of 1483174 and 1482570.
(so it is probably not due to the cpu as I first assumed)
The issue with kvm is perhaps different.

Comment 4 Laura Abbott 2017-08-23 18:22:51 UTC
The v4l2 backtrace is a known issue with a fix pending in tree but not yet built. Please file a separate bug for the kvm-intel issue.
