Kernel 6.4.6 compiled from source worked AOK on my desktop with Intel Xeon cpu and Nvidia graphics - see below for system specs. Kernels 6.4.7 & 6.4.8 also compiled from source with identical configs hang with a frozen boot terminal screen after a significant way through the boot sequence (e.g. whilst running /etc/profile). The system may still be running as a sound is emitted when the power button is pressed (only way to escape from the system hang). The issue seems to be specific to the hardware of this desktop as the problem kernels do boot through to completion on other machines. A test was done with a different build (from Porteus) of kernel 6.5-RC4 and that did not hang - but kernel 6.4.7 from the same builder hung just like my build. I apologise that I cannot provide any detailed diagnostics - but I can put diagnostics into /etc/profile and provide screenshots if requested.

Your best chance of getting it fixed is performing regression testing: https://docs.kernel.org/admin-guide/bug-bisect.html

Also, can you attach dmesg and system log output (like journalctl)?

Sadly system never gets to the point where dmesg can be run. I'll see if I can capture it before the system freezes. 6.4.9 has the same problem as 6.4.7 and 6.4.8. I'm pretty sure it is a graphics problem of some sort. Given that each kernel build takes c. 30 mins - the bug-bisect regression testing suggestion is challenging to say the least!
Boot without any options that hide kernel output, including "quiet". If you some some kernel messages, try to capture them, e.g. take a photo and upload it here.

Created attachment 304813 [details] attachment-4825-0.html 6.4.9 built with unconn.c from 6.4.6 builds and boots and runs fine. Thanks everybody.
Moved here: https://gitlab.freedesktop.org/drm/nouveau/-/issues/255
Commit 1b254b791d7b7dea6e8adc887fbbd51746d8bb27 should fix this.
Lets hope so.... https://git.kernel.org/pub/scm/linux/kernel/git/next/linux-next.git/commit/drivers/gpu/drm/nouveau?h=next-20230818&id=1b254b791d7b7dea6e8adc887fbbd51746d8bb27 says: It might not fix all regressions from commit 2b5d1c29f6c4 ("drm/nouveau/disp: PIOR DP uses GPIO for HPD, not PMGR AUX interrupts"), but at least it fixes a memory corruption in error handling related to that commit.
Sadly..... built 6.4.11 with the patched drivers/gpu/drm/nouveau/nouveau_connector.c and it still hangs on boot....
To communicate with nouveau developers please use their bug tracker instead. Your comments here are not sent to anyone. Thank you.
FWIW, does latest 6.4.y now work for you? It might be due to this change https://lore.kernel.org/all/20230821194136.393887865@linuxfoundation.org/
Sadly no - neither 6.4.12 nor 6.5 boot If I revert to version 6.4.6 of /drivers/gpu/drm/nouveau/nvkm/engine/disp/uconn.c and build the kernel with that, then that boots. https://gitlab.freedesktop.org/drm/nouveau/-/issues/255 is where the issue is being tracked.
