Description John Brooks 2017-01-10 19:49:40 UTC

Description of problem:

After updating to 4.8.15, my sound device disappeared, boot and shutdown started taking much longer, and I'm seeing errors including a BUG in dmesg. These go away after removing the `intel_iommu=on,igfx_off` option or downgrading to 4.8.8. I want to keep iommu, of course.

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

bad: 4.8.15-300.fc25.x86_64
known good: 4.8.8-300.fc25.x86_46

How reproducible:

100% for this machine, have not tested elsewhere

Steps to Reproduce:
1. Reproduced using a Dell XPS 13 9343
2. Boot with intel_iommu=on,igfx_off

Comment 1 Laura Abbott 2017-01-17 01:15:32 UTC

*********** MASS BUG UPDATE **************
We apologize for the inconvenience.  There is a large number of bugs to go through and several of them have gone stale.  Due to this, we are doing a mass bug update across all of the Fedora 25 kernel bugs.
 
Fedora 25 has now been rebased to 4.9.3-200.fc25.  Please test this kernel update (or newer) and let us know if you issue has been resolved or if it is still present with the newer kernel.
 
If you have moved on to Fedora 26, and are still experiencing this issue, please change the version to Fedora 26.
 
If you experience different issues, please open a new bug report for those.

Comment 2 John Brooks 2017-01-17 03:44:19 UTC

Reproduces in the same way with 4.9.3-200.fc25.x86_64:

Comment 4 Alex Medvedev 2017-02-08 15:29:54 UTC

I've got the same bug on my lenovo laptop with gentoo. As result the laptop is unbootable with recent kernels. Looks like 4.8.12 patch breaks iommu. There are 2 iommu changes in 4.8.12 which could be relevant, see https://www.kernel.org/pub/linux/kernel/v4.x/ChangeLog-4.8.12. Probably we should contact upstream.

Comment 5 John Brooks 2017-03-29 02:18:53 UTC

Still reproduces with 4.10.5-200.fc25.x86_64.

Guidance on how to bring this to upstream would be appreciated. I don't have the time to reproduce it on a vanilla kernel first.

Comment 6 Alex Medvedev 2017-03-29 09:45:02 UTC

The things was fixed for me in 4.10.6; 4.10.5 also worked; 4.9 version just wasn't able to load the i915 driver at all. igfx_off option is not necessary  anymore.

Comment 7 Alex Medvedev 2017-03-29 09:45:47 UTC

I have Gentoo just in case

Comment 8 Justin M. Forbes 2017-04-11 14:42:18 UTC

*********** MASS BUG UPDATE **************

We apologize for the inconvenience.  There is a large number of bugs to go through and several of them have gone stale.  Due to this, we are doing a mass bug update across all of the Fedora 25 kernel bugs.

Fedora 25 has now been rebased to 4.10.9-200.fc25.  Please test this kernel update (or newer) and let us know if you issue has been resolved or if it is still present with the newer kernel.

If you have moved on to Fedora 26, and are still experiencing this issue, please change the version to Fedora 26.

If you experience different issues, please open a new bug report for those.

Comment 9 Justin M. Forbes 2017-04-28 17:15:01 UTC

*********** MASS BUG UPDATE **************
This bug is being closed with INSUFFICIENT_DATA as there has not been a response in 2 weeks. If you are still experiencing this issue, please reopen and attach the 
relevant data from the latest kernel you are running and any data that might have been requested previously.
