Hi,

I'm encountering my second wave of reiserfs filesystem corruption with a 
Web/NFS/NIS server.  This time, I had fatal corruption after updating 
the Kernel.  Below are the system specs and the error message that I'm 
receiving.

The system:

Debian (latest unstable)
2.4.22 Kernel  (not patched in any way)
running NFS (from the kernel), which serves home directories to 3 
workstations
Software RAID 1
-2, mirrored 80gig (7200RPM) IBM hard drives
-Each drive is connected to its own channel on a Promise Ultra ATA/100 
Controller (Ultra100 Tx2) card (PCI)  (using ATA 100 cables)
-the two drives are called hda and hdc (contain 3 mirrored RAID partitions)

The problem:

Two of three RAID'ed partitions have been working without errors (/home 
and /usr).  My root partition generated the errors below for many days 
until  detected.  After a reboot, the system would not load.  reiserfsck 
--rebuild-tree could not recover the corruption.  I have assumed that I 
must rebuild the system now, and being able to prevent the errors below 
from happening again will affect how I proceed with the rebuild.  Any 
info for prevent the below errors would be great!

-Steve
