    Hi all,
    I’m just playing with RPI 3 B+, about 50% of boot attempts fail with kernel panic, regardless if it is a hot or cold bootstrap.

    I created the SD card with this command:
    dd if=ZeroShell-3.9.0A-RPI.img of=/dev/sdb bs=1M conv=fsync status=progress

    I also tried with bs=4M and without conv=fsync, same result.

    Any suggestion?

    Tnx
    V.S.

    I know the issue on Raspberry Pi 3B+.
    I’m investigating about the cause.

    to get rid of kernel panic you shoud uncomment hdmi_safe=1 and hdmi_force_hotplug=1 in config.txt

    Thanks Itzo for the suggestion, but in ZS 3.8.2 (3.9.0 doesn’t boot) i’m not able to find any “config.txt” (referred also here https://www.raspberrypi.org/documentation/configuration/config-txt/video.md) in the entire filesystem.
    hdmi_safe=1
    hdmi_force_hotplug=1
    Where can i define those options in ZS?

    Thanks

    you should mount /dev/mmcblk0p1

    lsblk
    NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINT
    mmcblk0 179:0 0 14.9G 0 disk
    |-mmcblk0p1 179:1 0 319M 0 part
    |-mmcblk0p2 179:2 0 640M 0 part /cdrom
    |-mmcblk0p3 179:3 0 640M 0 part
    `-mmcblk0p4 179:4 0 2.1G 0 part /DB

    Thanks Itzo, i found it. config.txt is located in the first partition of the SD card (volume ZS-Axxxxx).
    I uncommented hdmi_safe=1 and hdmi_force_hotplug=1 but no luck.
    Perhaps it successfully boots more frequently than before but the problem is the same: frequent kernel panic on boot 🙁

    First time I installed on my pi, I didnt connect my USB keyboard, I had the same issue, but when I connected the keyboard it booted OK.

    The issue is still the same now if I dont connect the keyboard, and I still not figure out why, looking for a way to solve this.
