two more oopses 2.4.21-rc3-xfs SGI-XFS CVS-2003-05-23_05:00_UTC with ACLs, realtime, no debug enabled

["Jeffrey E. Hundstad" <jeffrey.hundstad@xxxxxxxx>]

Per request I've added the "-x" option to klogd.  Hopefully these next 
two oopses will help with the analysis.  For the record, this is an 
Pentium-3x2 machine with software raid-1 on PDC20269-IDE for about 160G 
worth of space.  This machine was stable on 2.4.18-xfs for months.  We 
upgraded to avoid the root-exploit.

This time a simple re-boot did not bring the system back to life.  We 
needed to remove the quota startup entries in the lilo.conf to make it 
start otherwise the quota check never finishes.
