Is it a crash related to: Facing crash issues in Kwin-x11 5.14.5
Can you try the proposed workaround (updating mesa).

aftr trying this

echo “deb http://ftp.uk.debian.org/debian/ unstable main contrib non-free” >> /etc/apt/sources.list
sudo apt-get update
sudo apt-get -t unstable install libgl1-mesa-dri

board does not boots to ui, it stops at terminal login.

Facing same issue after applying work-around.

if it doesn’t reboot can you journalctl --boot=0 > journal.log and attach that? (Or if it rebooted, then use --boot=-1)

@robclark,Thanks for the reply.
This rootfs is not having the work-around. While trying to install some packages board crashed to login screen.

hmm, I was expecting to see Xorg logs in the journal… maybe you need to attach /var/log/Xorg.0.log from the two cases?

rob,

libgl1-mesa-dri is 18.3.6-2

journalctl --boot=0 > journal.log - https://pastebin.com/AY15isJB
Xorg.0.log - https://pastebin.com/RSy5Aw1R

not really seeing any useful hint in the logs. Any chance of attaching gdb to Xorg process before it crashes and getting a backtrace?

can you get that with mesa debug syms installed?

(I think on debian that would be something like ‘apt install libgl1-mesa-dri-dbgsym’)

rob,

installed the libgl1-mesa-dri-dbgsym in debian.

here is the latest gdb log

if i try to use the 19.3.1-4 unstable version Xorg will not load.
