[SOLVED] KERNEL PANIC - NOT SYNCING, 6.9.2, Boots in safe mode only

Title says it all.  Here's a photo of where it hangs.  I've tried flashing to a different USB (same model),  but that didn't work.  It does boot in safe mode.  

 

But where do I go from here?   

 

Is it possible to revert back to 6.8.3?  In unRAID it looks like there's an option.  But it doesn't seem to be functional.

Actually I found the exact cause.  Apparently I can't competently delete something from the syslinux.cfg file.  I got tire of seeing this warning from the fix common problems tool:

 

vfio-pci.ids or xen-pciback.hide found within syslinux.cfg. For best results on Unraid 6.9+, it is recommended to remove those methods of isolating devices for use within a VM and instead utilize the options within Tools - System Devices. See HERE for more details

 

I tried following the directions I saw here twice.  But apparently I don't know what I'm doing.

@Marc_G2 Looks like it cannot find the rootfs. Syslinux should look similar to this as a minimum.. You may have additional options after the bzroot.

 

default menu.c32
menu title Lime Technology, Inc.
prompt 0
timeout 50
label Unraid OS
  menu default
  kernel /bzimage
  append initrd=/bzroot 
label Unraid OS GUI Mode
  kernel /bzimage
  append initrd=/bzroot,/bzroot-gui 
label Unraid OS Safe Mode (no plugins, no GUI)
  kernel /bzimage
  append initrd=/bzroot unraidsafemode
label Unraid OS GUI Safe Mode (no plugins)
  kernel /bzimage
  append initrd=/bzroot,/bzroot-gui unraidsafemode
label Memtest86+
  kernel /memtest

 

Or if you click on flash within GUI. Ignore the addition entries I have.

So this is my syslinux.cfg file that currently works.   I thought I just needed to delete vfio-pci.ids=1022:43c7,1b73:1100

Is that not right?  I attached my broken .cfg file.  I know using notepad can cause issues.  But I figured it would've fine for this.

Click on flash drive in Main tab. 

This will bring up the syslinux. You can just delete the vfio part click apply.

Windows notepad saves things with Windows line endings, and in general is just awful. If you work with Linux-based files in the future, consider a replacement such as Notepad++, Programmer's Notepad, Atom, or similar. It's generally safer, and they're all free.

 

 

@Marc_G2 - Just to clarify, what's the state of things? Still booting to a kernel panic normally, but seems okay in Safe Mode? It might be best to copy your Config directory, erase the flash, and start over. The Config directory is the only directory which contains system-specific information on the flash drive. You're experiencing odd behavior, one of the files may have been mangled by a bad tool, and it doesn't seem like there are any customizations in place (aside from /config ) that you need in place, correct?

Ah yes, thanks.  It'd been so long since I configured my VM, I completely forgot about that.

The issue is resolved now.  I just need to edit it the correct way
