From your dmesg, you need to figure out why it is assembling only 5
out of the 6 disks, is it kicking a non-fresh one out of the array, or..?

RAID10 conf printout:
dmesg (/var/log/messages as well) are mysteriously quiet about why the resync
was initiated, they merely state that it is being done. That what is driving
me nuts, no log info. This is an ICH10 system board (Gigabyte GA-EP43-DS3L),
^^^^^^^^^^^ (see below)
the other board was Asus P5N-T Deluxe, also an ICH10 chipset. This is the
dmesg output from the recent Gigabyte board boot (and resync):
Linux version 2.6.27.7 (root@localhost) (gcc version 4.3.2 (GCC) ) #1 SMP Sat
Nov 29 10:14:42 EST 2008
Command line: BOOT_IMAGE=linux root=801 quiet
^^^^^
Remove quiet from the command line, reboot, and hopefully it will tell you
why it kicked the drive out of the array, it should say "non-fresh drive"
kicking from array or something similar. The next thing would be upon
reboot is it possible the drives are not syncing/the raid is not shutting
down properly(?)--
1. Remove quiet from the boot options (in lilo.conf or grub.conf)
2. Send an updated e-mail with the boot message.
3. Try to capture all of the dmesg/syslog when you shutdown and send that
as well.
Also see below, are all of these drives on the -SAME- controller?

I see the mobo has 6 sata ports- they are all connected to the ICH10 6 ports
at the bottom of the board- right? e.g. You're not using any additional SATA
add-in card..?
Also see below, DISK 4 is missing (/dev/sdd) you should reboot or check your
logs and see if its /dev/sdd every time, also print the output of:
smartctl -a /dev/sda
smartctl -a /dev/sdb
smartctl -a /dev/sdc
smartctl -a /dev/sdd
smartctl -a /dev/sde
smartctl -a /dev/sdf
