Ubuntu 23.10 crashes Dell Precision on shutdown

[Phil Buckley]

System hangs on shutdown with Ubuntu logo and manufacturers logo. Doesn't matter how long I wait. Fans remain on. Only way to restart computer is to press and hold power button for many seconds. Shutdown (suspend) blanks the screen and never recovers, but sleep after period of inactivity works fine.

System Dell Precision Tower 3420 Xeon e3-1270 v5 x 8 cores 32GB RAM Nvidia Quadro K1200 graphics. Latest updates on Ubuntu 23.10 booting from NVMe SAMSUNG 512GB. TP-Link Archer T4U v2 [Realtek RTL8812AU] Wifi on USB. ASUS USB-BT500 on USB.

Dual boot Windows 10 boots and shuts down normally.
Boot from Live Fedora 37 USB works fine -- (kernel 6.2??, is this a 6.5 problem?)
Boot from Live Ubuntu 23.10 USB fails on shutdown.

I think the issue may be fixed in a later kernel as described in this bug report https://bugzilla.kernel.org/show_bug.cgi?id=217995

I've tried installing 6.5.7 kernel but this still has shutdown fault

Today's 6.6.1 kernel fixes this problem
