HDMI Installation Caused Kernel Panic

Fri Jan 19, 2018 7:26 pm

Hello,

After installing the drivers and software for a 5" HDMI display and updating the pi, we got an "end kernel panic - not syncing: VFS: Unable to mount root fs on unknown-block (179,2)" error on boot up.

We have tried to change the code to "...(179,6)" but this did not work as well.

Is there a way to boot the pi back up to the desktop while keeping the software so that the display still works?

Thanks.

That means your filesystem is screwed and needs a fsck run on it. Nothing to do with HDMI, it's more likely caused by pulling the power.

Get another SDCard and USB reader. Download Raspbian Stretch and Etcher. Use Etcher to write Raspbian to the new SDCard. Boot that. Mount the bad SDCard in the USB reader. Open an LXTerminal window and run the following

sudo umount /dev/sda2
sudo fsck -f -y /dev/sda2
sudo poweroff


Swap the cards, and boot normally.

What drivers and software? A HDMI screen should just work with no added drivers or software.
Unless specified otherwise my response is based on the latest and fully updated Raspbian Stretch w/ Desktop OS.
