Your best chance of getting it fixed is performing regression testing: https://docs.kernel.org/admin-guide/bug-bisect.html (In reply to Peter Bottomley from comment #0) > 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).

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.

6.4.9 built with unconn.c from 6.4.6 builds and boots and runs fine.
Thanks everybody.
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. |
