Update of libc6 packages breaks graphics driver intel-i915-dkms

[Mike Ferreira]

Installed and recent system updates of packages:
libc6-dbg/jammy-updates,now 2.35-0ubuntu3.3 amd64 [installed,automatic]

After updates, third party Iris XE Grahics driver package intel-i915-dkms breaks. Says kernel release parse failure.

Worked fine before this update.

Ubuntu 22.04.3 LTS, Kernel 6.2.0-32.

Intel -9-13900K.

Attached crash Report.

[Mike Ferreira (mafoelffen)]

I know that package intel-i915-dkms is not an Ubuntu Package, but scheduled Ubuntu system updates of libc6 are what broke this driver.

Not actually sure what to do.

On the upstream Intel side, I have started a report to Intel. Will provide a link to that (here) when I finish it. In that, I will link back to this. (https://community.intel.com/t5/Graphics/Ubuntu-intel-i915-kdms-error-on-update/td-p/1524576)

It has to be somewhere in-between the two, so I thought I would cover both bases.

As I support Ubuntu users for the Linux graphics layer and Ubuntu hosted visualizations, this seems to be a good test case on the resolution of this.

Hi, thanks for the report.

I was able to reproduce what seems to be the symptoms on a fresh VM with the previous version of glibc:

This should be investigated by the Intel team, as the failure really doesn't tell us much about what happened. Marking as Invalid as evidently the glibc SRU isn't at fault.

[Mike Ferreira (mafoelffen)]

If you look at the Link to Intel, their Internal Support Team is looking at it now.

I know this is an upstream issue with their code. But I figure the left hand needs to know what the right hand is doing, and I would document it so we "all" know what affects each other.

I will update this when we know is it resolved, as it affects Ubuntu Users using their i915 drivers.

Status Update:

The Intel Graphics Team's original suggested work-around suggested (https://dgpu-docs.intel.com/installation-guides/ubuntu/ubuntu-jammy-arc.html) was for Ubuntu 20.04 and downgrading to the 20.04 OEM Kernel series for that... 5.17.0-1020-oem

Their current updated installation guide (https://dgpu-docs.intel.com/driver/client/overview.html) is for 22.04 and states that it needs a minimum kernel 5.19.0 and better if on the 23.04 series of kernels.

With the upstream upgrade of GLIBC 2.37 (updated on 2023-09-12), intel-i915-dkms fails on any 6.2 and higher series of kernels.

I downgraded 22.04 to it's OEM series, which is at 6.1.0-1020-oem. That fixes the intel-i915-dkms crash, but it still fails on on current libva, so still is broken as any 'working' work-around.

I added a tickler to the Intel Graphics Team that 23.10 releases in 3 weeks with kernel 6.5 and GLIBC 2.38, and that 24.04 releases in less than 7 months.

What Intel seems to be over-looking, is that this all worked with the current kernel series before the recent updates on GLIBC 2.37.

I know this is all their upstream code, and I am actively working with them, trying to get this working for current Ubuntu and it's Users.

That is where this is at at the moment.
