Hi, I'm having a lot of messages like this:

Oct 15 11:07:24 socrates kernel: interrupt storm detected on "irq23:";
throttling interrupt source

My dmesg info is:

atapci1: <Intel ICH7 SATA300 controller> port
0xe400-0xe407,0xe080-0xe083,0xe000-0xe007,0xdc00-0xdc03,0xd880-0xd88f
mem 0xfebff800-0xfebffbff irq 23 at device 31.2 on pci0
atapci1: AHCI Version 01.10 controller with 4 ports detected

And my disks are:

ad4: 238475MB <Seagate ST3250820AS 3.AAE> at ata2-master SATA150
ad6: 0MB <Config Disk RGL10364> at ata3-master SATA300
ad8: 238475MB <Seagate ST3250820AS 3.AAE> at ata4-master SATA150
ar0: 238472MB <Intel MatrixRAID RAID1> status: READY
ar0: disk0 READY (master) using ad4 at ata2-master
ar0: disk1 READY (mirror) using ad8 at ata4-master

Some days ago, I tried to test the RAID1 array, without success.
I removed one disk (the mirror disk) - in cold, and the system didn't
boot. I got an error in ad6.
But ad6 is an Config disk, I'm not sure, but this disk is not
important, or is it?
