You got it:
[EMAIL PROTECTED] kernels]$ diff -bd -U 0 <(sort config-2.6.20-rc5-git3-1 )
<(sort config-2.6.20-rc5-git3-debugging-2 )
-# CONFIG_DEBUG_LIST is not set
+CONFIG_DEBUG_LIST=y
-# CONFIG_DEBUG_MUTEXES is not set
-# CONFIG_DEBUG_RT_MUTEXES is not set
-# CONFIG_DEBUG_RWSEMS is not set

+CONFIG_DEBUG_MUTEXES=y
+CONFIG_DEBUG_PI_LIST=y
+CONFIG_DEBUG_RT_MUTEXES=y

+CONFIG_DEBUG_SLAB=y
-# CONFIG_DEBUG_SPINLOCK_SLEEP is not set
-# CONFIG_DEBUG_VM is not set
+CONFIG_DEBUG_SPINLOCK_SLEEP=y
+CONFIG_DEBUG_VM=y
But no additional debugging messages showed up; just a similar
kernel panic at bringing up networking.
If you want to take a look, I've placed the root filesystem and
the new debug-enabled kernel at http://ford.stearns.org/uml/ , along with
the command used to invoke.
Cheers,
