Stable SATA pci card for FreeBSD 6.x/7.0

[Sebastiaan van Erk]

Hi,

I'm running FreeBSD 6.3 (I know, I should upgrade), and I just bought an 
add-on pci SATA controller for 2 extra SATA disks.

However, a lot of disk activity on the drives will often cause the 
machine to crash and spontaneously reboot. I checked out which chipset 
was on the card with pciconf -lv and I found it was the Sil 3512. 
Googling showed me that I'm not the only one with problems using this card.

Does anybody have experience with a (preferably not too expensive) 
2-port SATA expansion card which does not have any issues running under 
FreeBSD 6.3/7.0?

[pciconf -lv output]
atapci0 at pci0:10:0:      class=0x018000 card=0x35121095 chip=0x35121095 
rev=0x01
hdr=0x00
     vendor     = 'Silicon Image Inc (Was: CMD Technology Inc)'
     device     = 'Sil 3512 SATALink/SATARaid Controller'
     class      = mass storage
