[Bug 2036452] Re: Update of libc6 packages breaks graphics driver intel-i915-dkms

[Mike Ferreira]

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.
