    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.

    I had to come back to say that the configuration: RPI 3B e ZS3.8.2A really working without this kernel panic bug.
    I have restored my profile from 3.9.0 to 3.8.2a and it workd very fine!

    Fúlvio, congratulations, you did a very nice work with ZS.
    Iam going to support this work!

    cya guys

    Hello, I am also having the same problem, I have a Raspberry Pi 3+ and it is failing to start with kernel panic, can anyone help? I noticed that changing the line dwc_otg.lpm_enable = 0 to 1, the kernel in panic did not give more problem, however the usb and network interface does not work that way, will the panic problem in the kernel be something related to these peripherals? help!
