I'm a newbie in ubuntu.

I want to get help because I'm facing a kernel panic problem like below.

enter image description here

So I googled and found some solutions and tried.

Solution1. Tried another version of kernel and its recovery mode.

enter image description here

I tried all of them. And they showed same kernel panic and exitcode=0x00000100.

Solution2. Made Ubuntu 18.04 LTS Live USB and tried to boot with USB.

But my computer displayed nothing then.

Solution3. Tried to boot manually in grub2 command line following this link. https://www.linux.com/training-tutorials/how-rescue-non-booting-grub-2-linux/

But in grub, I couldn't found any sda or other device in /dev directory enter image description here

Thanks for reading and apologize for my poor English.

First check your file system...

  • boot to a Ubuntu Live DVD/USB in “Try Ubuntu” mode
  • open a terminal window by pressing Ctrl+Alt+T
  • type sudo fdisk -l
  • identify the /dev/sdXX device name for your "Linux Filesystem"
  • type sudo fsck -f /dev/sdXX, replacing sdXX with the number you found earlier
  • repeat the fsck command if there were errors
  • type reboot

Then test your memory...

Go to https://www.memtest86.com/ and download/run their free memtest to test your memory. Get at least one complete pass of all the 4/4 tests to confirm good memory. This may take a few hours to complete.

Solved all my issues by buying a USB 3. Micro SD reader. Was getting Kernal panic with the generic USB 2. Card reader supplied Looked on all sorts of forums. Everything pointed to an issue with the SD card. Flashed 3. Always same issue. All running smoothly now.
