Hello all,

I'm beyond stumped. I've built the kernel more times than I can count. (LFS-8.1). I have tried the book, then 'oldconfig', 'localyesconfig', 'defconfig', tried copying the running kernel .config. I've run lsmod, lspci. The kernel builds just fine each time. My issue is the exact same Kernel Panic each time, nothing changes it. I've read through all the 'kernel panic' threads and tried many different things.

System: Diamond Systems Helix SBC, "DMP Vortex86DX3 SoC".

Here's 5 attachments of screen shots of my booting system. Below is the output of lspci and lsmod and grub.cfg.

Any help with this is greatly appreciated.

Your SATA controller seems to be in IDE mode. Shouldn't be.
Anyhow, the only important piece of information is the (0,0) after kernel panic. This tells us your kernel is unable to access the hard drive. You should put your controller in AHCI mode and then enable the AHCI driver in kernel. Furthermore you need the partition table support and root filesystem support enabled in kernel as <*>, not as <M>.

Emerson,

Ok, I'll check that. I don't have any kernel options selected as <M>, they are all <*>. The lsmod / lspci is from the system running Xubuntu.

Thanks.

Emerson,

My system has a funky BIOS and chipset I guess. It doesn't support AHCI, it is IDE only. It will boot from a SATA DOM, it will boot from CD/DVD and USB. As well as from an external mSATA drive when the SATA DOM is removed and a jumper for 5VDC changed.

There's only IDE settings in the BIOS.

So I'm not exactly sure then what I need to configure in the kernel to get this to work.

Any other ideas? I'm stubborn and want to figure this out.

Than you need to enable PATA drivers in kernel and use piix4 or whatever it shows when booted into Linux.

Hi Emerson,

I got it to boot today, albeit not all the way, but past this problem. Thanks for the help. I hand edited the .config file (done this for years / I actually prefer it over the menuconfig), turned off AHCI and turned on all IDE and SATA.

The boot this morning stopped when fsck.ext4 failed, can't find the file. Disk has errors which couldn't be auto-fixed. So I'm working on this.

Thanks for your help and suggestions, they really helped.

Not good. First, you should not edit the .config by hand, there are dependencies in the kernel config and you are breaking them by manual edit. Second, IDE code is deprecated, it should not be used (don't know why it is not removed from kernel). There are PATA drivers to use with IDE devices. Third, cluttering your kernel with all possible drivers is not the idea of a nice clean and lean custom kernel.

Tip: use make nconfig

Hi Emerson,

Boots perfectly now, no errors. Nice and fast too.
