Ubuntu :: Building Raid Array Causing An IRQ Error, Logs Included?

I've been trying to create a RAID5 array with 4x1TB disks.

I'm using Ubuntu 10.10, uname output:

Linux dynamips 2.6.35-22-server #33-Ubuntu SMP Sun Sep 19 20:48:58 UTC 2010 x86_64 GNU/Linux

I have two of them connected to the on board ICH7 SATA controller (sdb and sdc), and two of them connected to an external Silicon Image SiI 3132 controller (sdd and sde). sda is my boot disk split into several partitions and is also connected to the onboard SATA.

Everything is working fine before I create the array, here are my hdparm outputs:

/dev/sdb:
Timing cached reads: 2958 MB in 2.00 seconds = 1478.89 MB/sec
Timing buffered disk reads: 360 MB in 3.02 seconds = 119.35 MB/sec
/dev/sdc:
Timing cached reads: 2940 MB in 2.00 seconds = 1469.77 MB/sec
