Kernel Panics on Thinkpad x230

B10bot · 06-23-2019, 03:07 PM

I got a Thinkpad x230 a few days ago and have been trying to install CRUX Linux. I have so far had no luck. The kernel I have compiled will not boot. When ever I start the computer, it goes to a grub prompt, like this:

Code:

grub>

This is because whenever I run grub-mkconfig -o /boot/grub/grub.cfg, no images are found. However this is not the main problem. If I specify manually specify the image to boot from and boot from it, I just get a large amount of text with this at the end:

Code:

[    2.561231] ---[ end trace 51e23bce2bbaf ]---

After displaying this, it just stops and doesn't do anything afterwords. I can't read most of the error messages, so I don't know what is going on, and the stuff I can read is mostly numbers. I figure that something is wrong with the kernel. I am using grub 2 as my boot loader, and installed it for UEFI.

Did it come with it's own kernel or no?
How and on what system did you compile the kernel?

As I said in the post, I compiled the kernel from the source, in /usr/src/linux-4.1948/. I did this by running the following commands, with my EFI system partition mounted at /boot/efi:

Code:

make defconfig
make menuconfig
make all && make modules_install
cp arch/x86_64/boot/bzImage /boot/efi/vmlinuz
cp System.map /boot/efi

After this I ran

Code:

grub-install /boot/efi
grub-mkconfig -o /boot/grub/grub.cfg

Neither of these yeilded any errors, but grub-mkconfig -o /boot/grub/grub.cfg did not find any kernel images, which suggests something is wrong with mine.

maybe grub-install --boot-directory=/boot/efi /dev/sdx ?
then run grub-mkconfig

Also, you can use another grub.cfg from any linux and edit it manually for partitions, etc then copy to /boot/grub

Running grub-install --boot-directory=/boot/efi tells me it cannot find a EFI directory, even though I clearly have one.

thats strange...I have limited experience with efi stuff
try using --force parameter maybe idk
You could possibly just use a symlink for grub to find the kernel in /boot/efi?

cd /boot/
ln -sf /boot/efi/vmlinuz vmlinuz

that might work then do grub-mkconfig?
is /boot/efi on same partition?
