Public bug reported:

I was shutting down my Ubuntu 25.10 as usual using the upper right icon to do a 
power off.

Instead of powering off the entire screen went to the Ubuntu
distribution purple colour, a Tux Ascii penguin motif and in big white
text a message was displayed which I think said ... "Kernel Panic.....
trying to delete Init process!" or words to that effect, with another
line below that showing an hex error code.

I thought at first I had a virus or something, so I rebooted and then
shutdown as usual not finding anything suspicious.

Unfortunately I didn't get to take a photo of the screen as the time.

I just did a quick search of the kernel source code to see if I can find 
anything that matches up... 
"kernel/exit.c" - line 920 appears to be the line that caused the error message 
--->
   panic("Attempted to kill init! exitcode=0x%08x\n",
        tsk->signal->group_exit_code ?: (int)code);

and "drivers/gpu/drm/drm_panic.c" seems to be the code that displayed
the full screen error with the penguin motif.

This may be a more severe incidence of the other shutdown hang up Bug
#2132294 I posted not long ago.

A bit more info about my system...
