Update: I've connected Kingston SSD instead of Transcend's. The same errors appear, but now there is a lot of them (> 30 instead of maybe 5 per my test with Transcend).

OTOH the VT6421A mini-PCI card is the only PCI device in system (not counting the on-CPU AHB-PCI bridge). The problem is also present (to a lesser extent) when I plug it into x86-64 machine (using mini-PCI adapter). The SSD works fine if connected to motherboard's NVidia MCP55 SATA controller. I have read the datasheet and tried some changes to PCI registers but it doesn't fix it. I'm going to test x86-64 + VT6421A + Kingston SSD combination soon. Unfortunately I don't have a (mini) PCI analyser... I will look at REQ/GNT and similar signals on PCI, though. -- Krzysztof Halasa -- To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
