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

[Mike Ferreira]

Unfortunately, that last update to intel-i916-dkms has a fatal problem
that breaks zfs-linux: zed, with kernels 6.2.0-x.

All tests were successful... Or so I thought. Everything (Graphics
related) worked. OOT modules built, VM's saw the iGPU of the host.
Everything worked until the machine was powered down. Then would no
boot.

This machine is ZFS-On-Root. The only pool that was still imported was
rpool. All 4 other pools: bpool: /boot; hpool: /home; dpool: data;
kpool: various datasets fro KVM... were not imported on the boot, zed
would not come up. /dev/zd0 didn't exist.

Booted fine on 5.15.0-x kernels.

Removed intel-i915-dkms. Everything booted fine again.

Asked upstream intel if they want to reopen the support case, or if they
want me to file another new case...

Why? This one builds the modules. That part is fixed. It just doesn't
work with zfs-linux: zed on those same kernels. Fixed a problem... I was
so excited that that it actually worked... But caused another (fatal)
problem.

In holding pattern with that install until I get word from them.
Installed Noble alongside it, and another instance of Jammy, so I can
continue my other test cases for the release. I don't want it to be
"totally out" committed & waiting another 4 months.

Dang. LOL.
