6.2 kernel won't boot, may be nvidia related?

[Jonathan Kamens]

After installing most recent Lunar updates, linux-image-6.2.0-18-generic won't boot. First attempt to boot hung with gpu-manager service and other services blocked, something related to nvidia seemed to be going wrong. Subsequent attempts blocked at systemd-modules, I believe. Reverting to 6.1, boots fine.

It did boot up enough on one attempt that I was able to SSH in, even though I couldn't log in on the console because it never got the point of starting up the session manager or init on the other VTs. I'm attaching a journalctl log from before the first reboot attempt. Perhaps there is something illuminating in there; I honestly can't tell.

Note that while trying to get it to finish booting the first time when I was SSH'd in I did kill some processes, so you'll see that in the log.

But just to reiterate, I attempted booting several times after that and it never came up to the point of being on the network.

I thought maybe it might be a DisplayLink issue, but the problem persisted even when I rebooted without the DisplayLink hub plugged in.

Note also that as I said above I had to revert to 6.1 to get it to boot, so you'll see that as the last (successful) boot attempt in the log file.

For info, I had the same problem using the nvidia-driver-470 package, with kernel 6.2 failing to boot, hanging at starting the gpu-manager service. However, I managed to login under a maintenance shell and switch to the nouveau driver, and am now booting normally and managing to login under Wayland.

Duplicate bug report LP #2012706 contains some more logs.

[Paul Dooley (pilotpaul)]

Please note that this also affects the nvidia-driver-470 package.

Correction to package name in comment #5:nvidia-graphics-drivers-470

[Paul Dooley (pilotpaul)]

Update: Installing the latest 470 driver (version 470.182.03) from the Nidia website resolves the problem for my GTX660. The version in the Ubuntu repositories is 470.161.03-0ubuntu2 as of the Lunar beta, so I guess this just needs the latest version packaging.

[Alberto Milone (albertomilone)]

The latest drivers should be available in Lunar now. Please upgrade, and see if it helps.

[Paul Dooley (pilotpaul)]

Apart from having to manually install the new versions of some of the dependencies (libnvidia-cfg1-470, libnvidia-fbc1-470, libnvidia-ifr1-470 and nvidia-utils-470), this now seems to be working.

[Heinrich Schuchardt (xypron)]

The upgrade of 515 worked fine I now can work with kernel 6.2.0-18-generic.

[Jonathan Kamens (jik)]

Working for me now as well.
