 I couldn't update just yet, but removed the kernel objdirs and
 rebuilt.
 
 No change.  My net4501 still panics the same as before.  Perhaps it's
 hitting another instruction or reading another register present in 586+
 CPUs, (Geode GX1, Crusoe) but not in 486 CPUs (AMD Am5x86 W/B)?
 
 The panic message remains:
