Although, the SiI3132 SATA controller card is listed as compatible, my system crashes when the MorphOS boot loader shows up.

This picture shows the errors when booting MorphOS 3.19, but it's the same errors with Morphos 3.20 which has boot loader 1.17.

Any idea what's wrong here?

You can see in this picture, just before the error occurs that you can press Enter to select a boot source. But that doesn't work anymore, it crashes immediately so there's no time to press Enter.
I guess this is an issue someone from Acube or bigfoot has to look for.

That's interesting, just today I tried adding a Sil 3132 PCIe card to my PowerMac G5, and MorphOS wouldn't finish booting (the Mac froze).
I was thinking of using this controller with a new SSD, but I've put that on hold for now.

Thanks for the feedback. This can be an issue with a particular card, or the SiI3132 compatibility in MorphOS in generally broken.
The first two(!) SiI3132 cards I tried even crashed my system immediately so that I wasn't even able to boot AmigaOS. So I ordered the exact card that was confirmed to work on my system (with AmigaOS at least).

That issue has definitely been reported for Sam460 by ACube to us but has not been fixed in MorphOS 3.20.
I will look into it for MorphOS 3.21.

The PMacG5 related issue is most likely completely unrelated to that, even if it shows a similar behavior in the end.
Using any PCIe card in the PMacG5 that is not graphics card , nor a rtl8168 network card has never been properly tested.

That's good to know, thanks!

This is the card (an eSATA card with a chip sil3132CNU)

The idea is to use it as a SATA2 controller to connect a Crucial or Samsung SATA2/3-compatible SSD for use in MorphOS, which would be better and more compatible than the PowerMac G5’s built-in SATA1 controller.
Do you have any suggestions? These cards usually have RAID enabled by default; perhaps it would be useful to disable it, but I imagine that would have to be done from a PC.
If you have any suggestions, I can try again.

In the hope that this might be helpful, I tried another SATA PCIe card (this one also has a sil3132CNU chip and allows you to use SATA or eSATA SSDs depending on the jumper settings), this model:

Unfortunately, the result is identical to that of the other card: MorphOS fails to boot properly (no video output), and after several seconds, the PowerMac G5’s fans can be heard running at full speed. In contrast, OS X Leopard boots perfectly and detects the SATA PCIe card, just as it does with the RTL8168 PCIe Ethernet card and the ATI Radeon X1950 Pro PCIe graphics card.
So I’m afraid I’ll have to put aside the idea of connecting a SATA2 SSD to the PowerMac G5 for now.
If there's anything else I can do, I'm here to help.

good news, I’ve figured out how to use a 1Tb SATA 2/3 SSD by installing it in the PowerMac G5’s SATA1 B bay (I left the 1TB HDD in the less compatible SATA1 A bay).
Although I can’t take advantage of SATA2/3 mode, but only SATA1, I’m still getting a respectable 130 Mb/s for both read and write speeds, while I wait for PCIe SATA 2 controllers to become available for the PowerMac G5 as well.
