>Description:
my system (AMD XP/1GB RAM) with one or two PCI SATA VIA 6421A continuously shows: - interrupt storm detected on "irq19:"; throttling interrupt source -.
It shows when the SATA disk(s) attached to the controller are more than little accessed.
- just tried ZFS mirror (or RAID1) configuration
- WD disks have been set (jumper) to SATA 150
- one or two SATA cards installed
- tried to move cards from one slot to other (no change)
- both when 1 disk per card or two disks on one card (ZFS mirror configuration)
- most of the unused onboard devices have been switched off in BIOS (serial/parallel ports, audio, midi, game, IDE2, floppy); just IDE1, USB and LAN active.
-tried with FreeBSD 8.0 and FreeNAS 7.0 (based on Freebsd 7.2)

>How-To-Repeat:
- PCI SATA VIA 6421A controller board
- two SATA disks in ZFS mirror (or 1 PATA+2SATA in ZFS raid1)
- heavy read/write load or "zpool scrub" starts errors
