I am getting the following kernel panic:  2.6.9-89.0.16.EL #1 Tue Nov 3 
17:15:02 EST 2009 i686 i686 i386 GNU/Linux
This system has ran fine for 2 years+.

Nov 17 10:09:21  kernel: Call Trace:

System has 1 GIG ram, SATA disk running in RAID-1.
/proc/mdstat shows everything is fine on the array.

It started to panic last week. I upgrade from 4.4 to 4.8 and same thing 
is still happening.

Looking back further in the messages  I see this also:
