Does anyone know is there are any stable SiI3132 drivers for the mac pro? (Preferably Intel 64-Bit, not Universal 32-bit) I can't manage to backup anything via eSATA without a kernel panic.
I built my own quad bay hot swappable SATA enclosure about a year ago and got a 4 port eSATA card to go in my G5. It worked wonderfully and reliably. When I got my Mac Pro I got a PCIe SATA card for cheap and decided to put a port multiplier into the drive enclosure to have only one cable, I don't need RAID speeds - just lots of storage. To make a long story short the UB Sil3132 drivers kp'd me all the time and I had to stop using the enclosure all together. Every last kp log pointed to the Sil3132 drivers. I went through two SATA card makers but the hardware looked identical and used the same drivers. I got the exact same results. AFAICT the Silicon Image drivers need lots of work for MacPros. I finally saw that Seritek released a final firmware for their PCIe SATA card that supports port multipliers. I grabbed one from macsales.com
http://eshop.macsales.com/item/Firmtek/SATA2SE2E/ for $100, about double the other 2 port cards, and all works perfectly now. The ironic thing is that Seritek uses the exact same hardware that the other two cards did but they make all their own drivers and firmware. There are no drivers to install, they load off the ROM on the card. You need to contact tech support to get the latest firmware flasher to work with the Mac Pro but I am incredibly happy with the card now and 4 days w/o a kp when I was getting them every couple of hours with the Silicon Image drivers.

PS. The Seritek card also can pass SMART status off to OSX, unlike the SilImage drivers, and they are supposedly working on making it bootable on MacPros too.
