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

[Mike Ferreira]

Copied from what I posted at:
https://community.intel.com/t5/Graphics/Ubuntu-intel-i915-kdms-error-on-
update/td-p/1524576#

To reproduce, Install Ubuntu Desktop 22.04.3 LTS with ZFS as the install method (In the install Method Panel under advanced options). I have 5 pools (rpool, bpool, hpool, dpool, & kpool), but it will fail with just the default 2 pools (rpool & bpool). Reboot. Log in. Install the Intel OOT drivers. All seems to work... Albeit, a problem just with some of the 'libva' libraries just when you try to run vainfo. --> xpu-smi & clinfo seem to show everything is working okay. Notes, the default install of desktop is which the HWE stack installed. ensure you have both linux-image-generic & linux-image-gerneric-hwe-22.04 installed
>>> apt list linux-image-generic-* --installed
For test purposes, so that you can get to the Grub2 menu, edit the /etc/default/grub file with these edits
>>> GRUB_TIMEOUT_STYLE=menu
>>> GRUB_TIMEOUT=5
>>> GRUB_RECORDFAIL_TIMEOUT=5
>>> GRUB_CMDLINE_LINUX_DEFAULT="--- --verbose debug drm.debug=0xe  intel_iommu=on"
Save. Pick up the changes:
>>> sudo update-grub
 
Reboot... 
 
With any kernel in the 6.2.0-X series: Will give an error saying something along the lines of "device /dev/zd0: file or device not found"... Then continue booting, taking a long time on udisk, the ending up at a root maintenance prompt. (Instead of the desktop). Hit Enter Key to go on. 
 
At the root prompt, if you do 
>>> zpool list
It will show that only rpool is imported. (bpool is not present) If you run
>>> zpool import bpool
>>> zpool list
All are imported fine. No matter what you do, if you boot from the ... Will result in the same.
 
Why? If you do
>>> systemctl status zfs-zed.service --no-pager
'zed' is inactive. It never starts. It will not start manually, and will not restart. <-- On a normal boot sequence with ZFS, the zed service should start, and you should see it import of each pool in the status... That is not happening at all.
 
If you boot any of the 5.15.0 series kernels, it boots normally...
 
I installed the OOT drivers on the second Ubuntu 22.04 LTS installation that is installed on LVM2, with no ZFS... same machine, just different location on it. It boots fine on 6.2.0 kernels.
