Hi all

 

I have been using Unraid for years and I just had my first kernel panic. Let me know if anyone knows how to fix this issue.

 

Thanks

SOLUTION

 

  1. Downloaded a copy of the 6.9.2 files
  2. Manually copied over all the bz* files
  3. Also moved the "syslinux.cfg-" file back into the syslinux folder; for some reason it had moved out to the main directory
  4. Reboot
  5. Relish

 

Now I just need to find a good way to automate backups of my flash drive

The screenshot shows a failure reading off the flash drive.

 

sometimes rewriting all the bz* type files for the release on the flash drive fixes this type of problem.

 

Well this worked.  I will edit my original post to mark as solved. Thanks!!!
