[CLOSED] New kernel 6.4.7 / 8 - boot hangs on desktop with Intel Xeon & Nvidia

[peebee]

Back to the subject of this thread.........
@BarryK @01micko @jamesbond and any other experts of long standing - have you ever seen anything like this? I'd like to report it to the Kernel developers but need some evidence of what the problem is!!!

My latest test involves a build of kernel-6.4.8 with AUFS=no - i.e. overlayfs only
I boot with a ydrv (attached) which comments out some lines in /etc/rc.d/rc.sysinit so that the boot gets as far as /etc/profile
which is also patched with set -x

and the boot then stops as shown - seemingly at a random shell line 33 ............

Driving me mad!!!

USER=`id -un`
PS1="# "
LOGNAME=$USER
HISTSIZE=1000
HISTFILE="$HOME/.history"
if [ -f /usr/bin/mp ] ; then
EDITOR=mp
elif [ -f /usr/bin/nano ] ; then
EDITOR=nano
else
EDITOR=vi
fi
PAGER=less
INPUTRC=/etc/inputrc
[ -d /usr/share/terminfo ] && export TERMINFO=/usr/share/terminfo

I raised this Kernel Bugzilla report:
https://bugzilla.kernel.org/show_bug.cgi?id=217776

and this resulted in identification of this Nouveau report:
https://lore.kernel.org/all/20230806213 ... ate.local/

Subject: 2b5d1c29f6c4 ("drm/nouveau/disp: PIOR DP uses GPIO for HPD, not PMGR AUX interrupts")
the patch in $Subject breaks booting here on one of my test boxes

https://cgit.freedesktop.org/drm-misc/c ... 5ede75f4ef

So some progress in that the cause may have been identified.....

@peebee - would something like

Code: Select all

modprobe.blacklist=nouveau

(or maybe drm_nouveau) appended to the kernel line allow you to boot?
