mdstat: resync=DELAYED

[Eric Pretorious <eric@pretorious.net>]

Hello, All:

I'm configuring a SuperMicro 5013CM8 (with on-board Adaptec AIC-7902B U320 
SCSI controller controlling two Seagate ST373207LC 73GB U320 hard-drives) and 
am experiencing random crashes: The system ocassionally blurts out a bunch of 
stuff about the SCSI system and then freezes.

Checking the contents of /proc/mdstat I see a potential red-flag:

%> cat /proc/mdstat
Personalities : [raid1]
read_ahead 1024 sectors
Event: 5
md2 : active raid1 sdb1[1] sda1[0]

      [======>..............]  resync = 30.4% (15410224/50660864) 
finish=56.9min speed=10315K/sec

What does this mean? How can I fix it?
