    HI,

    Please see bug report 1088524, Its the same but with more information.


    Please see attached boot log.

    Thanks for providing the full log. As I understand from the subject
    this is only aproblem with 3 screens. So if this is correct and with
    two screens all is green, do boot please with two screens and attach
    this full boot logs as well for comparision.

    In meanwhile there is as well newer kernel available, please upgrade
    to 6.1.129-1 and report back if the problem persist with the nwer
    kernel as well.

    Ideally if yes, then testing newer kernel from unstable or
    experimental would be great to determine if the issue is fixed.

    Thanks already.

    Thank-you for the boot logs Benjamin. The 3-monitor log initially
    confused me since it started with the 2-monitor log and looked
    identical. Once I'd figured it contained multiple boots and cleaned it I compared differences using:

    diff -u <( sed -n '/kernel:/ s/^.*kernel: \(nouveau.*\)/\1/p' /tmp/bootlog_2_screens.log ) <( sed -n '/kernel:/ s/^.*kernel: \(nouveau.*\)/\1/p' /tmp/bootlog_3_screens.log )
