Null pointer derefernece on module 'pinctrl_elkhartlake'

HiroyukiKosaka — Wed, 09 Aug 2023 01:42:39 GMT

A kernel module provided by ECI causes NULL pointer dereference. We do not know what this module does. Can we ignore this error? Does it have any impact for evaluation?

Please give us your advice. Thanks!

Hi HiroyukiKosaka,

Allow me to setup a system to reproduce the issue. In the meantime, could you confirm that you build the core-bullseye image from ECI? Could you share more details of the system that the image was installed on? Also, which version of ECI are you using?

Regards,

Jesus

Hi HiroyukiKosaka,

I built and installed the core-bullseye ECI target from ECI 3.0.2 and did not observe the error you are seeing. Please let me know if you used a different ECI target or ECI version. Thanks.

Regards,

Jesus

Sorry for the late reply. In Japan, companies were on summer vacation for the whole of last week, so I couldn't reply.

How to install ECI:
I would follow the link below.
Setup ECI APT Repository—ECI documentation (intel.com)
1. Perform BIOS settings as much as possible
2. Install pure Debian 11.7 on target
3. Install eci-customizations and linux-intel-rt packages using ECI APT Repository

OS and ECI version information is as follows.
Debian version: 11.7
ECI version: 3.0.2 (as of 2023/07/04)

Also, the version/build information about the CPU/BIOS is as follows.
Client Silicon Version: 0.2.0.15
Project Version: EHLSFWI1.R00.3162.A01.21041311432
Build Date: 14:32 04/13/2021

Thanks,

Kosaka

Hi Kosaka,

No worries! Thanks for providing the additional information. Would you also share some hardware details? What system are you using and what processor?

Hi,

The issue should fix in EHL MR3 BIOS per https://bugzilla.redhat.com/show_bug.cgi?id=1948468#c11

Can you update the BIOS to test?

Thanks for your help. I was able to complete the installation without any issues on the board with updated BIOS. Therefore, this issue is now resolved.
