Kernel Panic on real hardware. (not a dupe)

SamHep0803 opened this issue 6 years ago · comments

I keep getting the same error as with the other issue, but the only difference is that I'm trying it on real hardware.

To be specific a PC with windows installed on it. However, I'm having trouble getting it to even boot as I'm getting a kernel panic. Also, I'm using the Makefile provided.

To be honest, I have no clue what to do.

Thanks, Sam.

My guess would be that the kernel doesn't have the required components built in to support your system. But I can only speculate without more information. What are you using to boot? What does the kernel panic say exactly?

As I said, it's the same error as the last kernel panic issue. However, It works in qemu, just not my test system.

kernel panic - not syncing vfs unable to mount root fs on unknown-block (0 0)

There.

I'm using a custom build system

Would be grateful for a reply?

Sorry, I have very little time these days. I may be overlooking something, but which previous kernel panic issue are you referring to?

As issued in #8 .

Ah, i see, could you tell me what kind of system you're currently using to build and could you give me the output of 'fdisk -l image'?

I'm currently using Ubuntu 18.04 LTS and fdisk shows:

It might not be able to interpret PARTUUIDs, i suggest editting gen_image.sh to set root=PARTUUID=..
to root=/dev/sda1 or root=/dev/sdb1, whatever works, and trying again.

Michiel Derhaeg · Answer 10 · Sun May 27 2018 02:38:05 GMT+0800 (China Standard Time)

Or just by mounting, and manually editting /boot/grub/grub.cfg, whatever floats your boat.

Samuel Hepworth · Answer 11 · Sun May 27 2018 02:38:51 GMT+0800 (China Standard Time)

So should I set it to what my USB drive is mounted at now?

Michiel Derhaeg · Answer 12 · Sun May 27 2018 02:42:15 GMT+0800 (China Standard Time)

If you're using the same system to boot it, yes. It might be slightly non-deterministic but it's probably right.

Samuel Hepworth · Answer 13 · Sun May 27 2018 02:44:04 GMT+0800 (China Standard Time)

No, I'm not using the same system. It's a different system with a windows SSD in it.

Michiel Derhaeg · Answer 14 · Sun May 27 2018 02:50:58 GMT+0800 (China Standard Time)

In that case you'll have to do some trial and error.

Samuel Hepworth · Answer 15 · Sun May 27 2018 02:52:31 GMT+0800 (China Standard Time)

i seem to be getting the same error o
in vbox now.

Michiel Derhaeg · Answer 16 · Sun May 27 2018 02:54:09 GMT+0800 (China Standard Time)

It's hardware specific, so trying it first in vbox has no use.

Samuel Hepworth · Answer 17 · Sun May 27 2018 02:55:29 GMT+0800 (China Standard Time)

the only reason im trying it in vbox is bc it was working before

Samuel Hepworth · Answer 18 · Sun May 27 2018 03:00:43 GMT+0800 (China Standard Time)

So, I booted it up on my machine again only to find out I have another kernel panic. Buuut it's a different error. I can't see the whole error but the last line reads.

Michiel Derhaeg · Answer 19 · Sun May 27 2018 03:08:19 GMT+0800 (China Standard Time)

Have you tried other options? You might have selected the Windows disk. Also, it just occurred to me that the kernel configuration you used might not have the required components enabled to boot from your particular system and USB drive. Configuring that correctly might be difficult for someone who hasn't done that before.

Michiel Derhaeg · Answer 20 · Sun May 27 2018 03:11:35 GMT+0800 (China Standard Time)

Usually kernels are built to support all sorts of hardware, but in this case it's mainly to support VM's.

Samuel Hepworth · Answer 21 · Sun May 27 2018 03:15:41 GMT+0800 (China Standard Time)

Hmm I’m sure I didn’t select my windows drive and even after changing the gen-image.sh file my vm still didn’t work. I’m stumped at this point.

Michiel Derhaeg · Answer 22 · Sun May 27 2018 03:18:50 GMT+0800 (China Standard Time)

Well, so am I, I'm guessing it's a kernel configuration issue. And those sorts of things are way to hard to diagnose like this :S

Samuel Hepworth · Answer 23 · Sun May 27 2018 03:22:46 GMT+0800 (China Standard Time)

Ugh... Well I’ll have to call it a day till I get back to my PC, do you have discord?

Michiel Derhaeg · Answer 24 · Sun May 27 2018 03:43:56 GMT+0800 (China Standard Time)

Yep, send me a mail about it when you want to get in touch.
I'm going to close this issue for now.
