I blacklisted nouveau and booted into a 6.1 kernel:
% uname -a
Linux xps 6.1.0-9-amd64 #1 SMP PREEMPT_DYNAMIC Debian 6.1.27-1 (2023-05-08) x86_64 GNU/Linux

It has been running without problems for nearly two days now:
% uptime
08:34:48 up 1 day, 16:22, 2 users, load average: 1.33, 1.26, 1.27

Regards,

Nick.
