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.
