Man, this is weird. Do you happen to have a addonics device too? I have one 4726 and two 3726s here and none shows such problem. Also, there are quite a few people confirming that detection is okay on 3726 and 4726s. The failure you're seeing is very similar to what happens on my 4726 if the first fan-out port is not occupied. 4726 behaves very strangely when its first port is empty. Even BIOS has to time out on 4726 if the first port is empty, so I've been thinking it's the peculiarity of the chip (and considering the shitty ATA emulation of the pseudo config device I'm not surprised). Also, marvell PMP and new generation of SIMG PMPs (5723 and friends) work fine with the current code. I've never used windows or the binary only Linux driver. Do they work fine when the first port is unoccupied? Also, is your PMP from addonics? In most reports, they're saying the array is addonics. I'm not sure whether it's because that vendor is so popular that there aren't many alternatives or their hardware is somehow quirky. -- tejun
