Here's the full trace, #7 cuts off the start of the BUG:

On my Alder Lake system this appears to be a failure to load the Intel
driver in some way.
I get the following error in XOrg.0.log on 5.19.0-18:
[ 3.817] (EE) open /dev/dri/card0: No such file or directory
On 5.19.0-15, it loads the card correctly, and that device does exist.

I just ran into a 12.04.03 client, and it does have the problem.

Hmmm. Hard to say. The server was at 12.04.02 when I took over
management of the systems, and I upgraded the clients to 13.04 and the
server to 12.04.03 at about the same time, so it's hard to disentangle
which change caused the problem. I certainly had 12.04.02/12.04.02
