Hello! Long story. Get some coke.
I'm having an odd problem with using software raid on two Western
Digital disks type WD2500JD-00F (250gb) connected to a Silicon Image
Sil3112 PCI SATA conroller running with Linux 2.6.20, mdadm 2.5.6
[[ .. snip .. ]]
See comments below.

My main question:
Why the 'heck' are you running a RAID1 with a master/slave combination?
That is probably the -worst- way to run it. When using any form of RAID,
make sure you do not share an IDE channel for any one raid device.
Advice? Hook up each drive as a master, then your rebuild speed should go
to 30-60MB/s.
Traditional Troubleshooting:
What does fdisk -l /dev/hda
fdisk -l /dev/hdb
Report?
Also,
What does:
smartctl -a /dev/hda
smartctl -a /dev/hdb
show?
Then,
smartctl -t short /dev/hda
smartctl -t short /dev/hdb
Wait 5-10 minutes, re-run the commands (-a) above.
Then,
smartctl -t long /dev/hda
smartctl -t long /dev/hdb
Then re-run the (-a) smartctl above.
--------
Those errors look really weird, I would separate the two disks, each on
their own IDE channel and see if your problem goes away.
