Kernel panic on attempting to run KLV-Spectr-alpha2 iso from USB

Hi all,

When trying to install KLV-Spectr on a laptop I have, it crashes out with a kernel panic, exit code 0x00000100. I am unable to see the entirety of the error output as it scrolls past the screen. I do, before it crashes, get to this menu, where I can choose a lot of different options for launching it, and I chose default. Some stuff comes up on the screen, then it exits with that kernel panic.

This issue is happening with 2 separate USB sticks that I am trying (as I see this topic may be related, and this user suspects it could be down to the USB stick used. https://www.forum.puppylinux.com/viewtopic.php?t=9010 ). I have also tried it with KLV-Spectr alpha2 and alpha3.

On the first USB stick, I used unetbootin which has successfully worked for me before for installing fossapup64. This, and the laptop is the same as I did use to install fossapup64 on. (I'm just experimenting a bit.)
The second USB I also used unetbootin. Both sticks were reformatted fat-32 before loading the ISO on.

I guess @rockedge will see this anyway, but as this is probably to do with KLV-Spectr ( https://www.forum.puppylinux.com/viewtopic.php?t=8619 ) which seems to be his project, I hope you don't mind me tagging.

Also, I changed the bios to use legacy boot instead of UEFI, as I thought that would help, but the issues are exactly the same.

Hope it's okay that I made a new topic, as I'm not sure which of the two linked threads would be most appropriate for my issue, as I'm not sure if it's a KLV issue or a USB issue or neither or both.

Thanks in advance,
jupy :)

@jupy I will look into this and I am about to post KLV-Spectr-beta1 which is a bit more polished.

I think what is happening is the boot menu selections are not quite set yet and this may be causing the kernel panic, which I have also experienced trying out different boot methods. Also I have not tested on anything but ext4 and ext3 formatted partitions.

what does the boot stanza look like that you are using that is resulting in the kernel panic?

We are still working out the kinks in this OS :thumbup2:

Thanks for the swift reply!

Yes, I've seen you make a few posts mentioning beta. I'll hopefully try that too, when you release it.

I'm not totally sure what the boot stanza means, but here's some pictures of my screen during the process! After it gets to the "Run /init as init process ......" part, it does spit out some other stuff faster than I can capture it.

Edit to avoid double posting:
I guess that not everyone is using the ISO to install. Is there another way?

@jupy Have you tried to set up the USB stick manually? It is relatively easy to do using a Puppy Linux to setup the whole system.

Use GParted to format the target USB stick :

1. FAT32 512 M set the boot flag for the FAT32 partition.
2. ext4 the rest of the drive storage capacity
Label the ext4 partition as "QEMU".

create a directory in the ext4 partition called /KLV-Spectr-beta1 (or whatever is appropriate) .

open the KLV-Spectr-beta1 ISO file and copy the contents to the directory /KLV-Spectr-beta1

run Grub4Dos on the USB stick from the FAT32 partition and let it install the boot loader and menu.lst to that partition (FAT32).

enter the USB stick ext4 partition and and cd into the /KLV-Spectr-beta1 directory and open a terminal then run ./wd_grubconfig

copy the terminal output the pertains to the Grub4Dos menu.lst. (these are the boot stanza's)

open on the FAT32 partition the file menu.lst and paste those boot stanza's near the top. Save the results.

close everything and un-mount the USB stick.

Now reboot and select the USB drive. Should, in theory, work........... 8-)
