In an ideal universe, the kernel never panics.

Mine however still does from time to time.

I have been informed that this is attributable to me continuing to use an
otherwise perfectly servicable AMD graphics card that the X maintainer
has elected to no longer support.

I have suggested that there might possibly be some more graceful failure
mode than a kernel panic in response to some unhandled condition, but to
no avail.

(Hardware upgrade has been pednding on my end for more than a year.  I have
all of the necessary parts... new motherboard, new CPU/APU and new memory...
however I just never seem to find the time.)
