Kernel update to 3.10.0-862.2.3.el7 killed my HP Proliant G4... error indicates that the BIOS has corrupted the boot something or other. (did not get that recorded) I switched to the backup BIOS, and booted from previous kernel ( all is fine again running kernel 3.10.0-693.21.1.el7 ) |
|
|
Exact same issue with kernel-3.10.0-862.3.2.el7.x86_64 ( i had to roll back to kernel 3.10.0-693.21.1.el7 ) |
|
|
Same here. I was able to workaround and boot by adding: blacklist snd-soc-hdac-hdmi blacklist snd-hdmi-lpe-audio blacklist snd-hda-codec-hdmi to /etc/modprobe.d/snd.conf (the second line likely making a difference, I din't have time to narrow it down). After adding the above lines and booting to new kernel you can trigger the crash by: modprobe snd-hdmi-lpe-audio and get the crashdump.

and... after recent Microcode update, now have random crashes with 3.10.0-693.21.1.el7 as well. Rolled back to "emergency kernel" 3.10.0.327 ... |
|
|
I'm seeing this as well. |
 |
Can someone do a test-install of ELRepo's kernel-ml [1] ? The current version is kernel-ml-4.17.0-1.el7.elrepo. This is to find out if the issue reported in this tracker has been fixed in the latest mainline kernel. [1] https://elrepo.org/tiki/kernel-ml |
|

I'm currently running 3.10.0-862.3.2.el7.x86_64 and I have several snd modules blacklisted. When I "modprobe snd-hdmi-lpe-audio" with this kernel the machine crashes. However, the kernel-el kernel 4.17.0-1 does not have the module snd-hdmi-lpe-audio and if I boot that kernel without any blacklisted snd modules no snd modules get autoloaded. So, I doubt this kernel has the relevant options enabled which, of course, would render this test useless. |
|
|
Hmm, you are right. kernel-ml does not have this module. Will see if it can be enabled. |
|
|
I have rebuilt kernel-ml with CONFIG_HDMI_LPE_AUDIO=m (kernel-ml-4.17.0-1.ay1.el7.x86_64.rpm) and uploaded it to: http://elrepo.org/people/akemi/testing/el7/kernel/ Please note that the packages are not signed. |
|
|
I can confirm that I, too, am having this problem, with 3.10.0-862.3.2.el7.x86_64, following two fresh installs on new hardware yesterday. I'm sorry all the evidence I have is a photo. Going back to the install kernel (3.10.0-693.el7.x86_64) is a workaround. I have installed kernel-ml-4.17.0-1.ay1.el7.x86_64.rpm as requested and can confirm the issue is not present there, at least for me. |
|
|
@madhatta Thanks for reporting the result with kernel-ml. Good to know that the fix is in the latest mainline kernel. Hopefully we can identify the patch that takes care of the current problem. |
|
|
The following upstream patch (commit c77a6edb6d4d35204673cad7389c317bfb17492e ) is a likely candidate that fixes the issue: https://patchwork.kernel.org/patch/10246971/ I built a kernel-plus package using the above patch ( kernel-plus-3.10.0-862.3.2.el7.bug14779.centos.plus.x86_64.rpm ). It is available for testing: https://people.centos.org/toracat/kernel/7/plus/bug14779/ |
|
|
Unfortunately, the decision was taken to put C6 on the hardware I was working on, for delivery-date reasons. I am expecting more of the same hardware shortly, and will attempt to continue testing and feedback at that time. |

[root@tux ~]# uname -a Linux tux.leun.net 3.10.0-862.3.2.el7.bug14779.centos.plus.x86_64 #1 SMP Tue Jun 12 22:32:06 PDT 2018 x86_64 x86_64 x86_64 GNU/Linux [root@tux ~]# modprobe snd-hdmi-lpe-audio System survived that - crashes without the fix. So, yup, can confirm. Thanks. |
|
|
@newton Thanks for the test result and the confirmation that the patch worked. The next official update to kernel-plus will include the patch. Now, the next step is to file a bug report with Red Hat at http://bugzilla.redhat.com to get this patch into the RHEL kernel. Then the CentOS kernel will inherit it. |
|
|
kernel-plus-3.10.0-862.3.3.el7.centos.plus has been released. It has the patch from this bug report. |
|
|
Well, this didn't solve it for me. (latest 3.10.0-862.3.3.el7 kernel crashes my system still). I guess I'll have to figure out how to get the crashlog and make a new bug report... |
 |
You need the centosplus kernel not the main distro one. |
|
|
Found and installed centosplus kernel, but it too crashes on boot. My system must have a slightly different bug than the one fixed... 20180618_164727_001.jpg (106,861 bytes) |
|
|
@mikerotec If the provided plus kernel does not fix the crash, your problem is most likely different. You might want to file a new bug report with all the details. |
|
|
RHBZ status: Originally opened as #1598592 (private) but closed as a duplicate of #1551742 (private). Currently marked "Verified". |
|

I am planning to build a new test version of kernel-plus that might fix other alsa-related issues. |

The following two patches have been added: commit 1967158fff819b38f4e46763ca8df067b4b69f59 "ALSA: x86: fix error return code in hdmi_lpe_audio_probe()" commit 7229b12f5da33d5c376ee264f063703844b8092d "ALSA: x86: hdmi: Add single_port option for compatible behavior" A patched set of kernel-plus is available for testing: https://people.centos.org/toracat/kernel/7/plus/bug14779_2/ (kernel-plus-3.10.0-862.14.4.el7.centos.plus.6) Feedback appreciated. |
|

RHEL 7.6 is out. The distro kernel (3.10.0-957.el7) now has all three patches in this bug report. Closing as 'resolved'. |
