"ata8.00: exception Emask 0x52 SAct 0x0 Serr 0xffffffff action 0xe frozen"
I am trying to install Ubuntu on a new desktop computer with an asus MAXIMUS FORMULA VII motherboard. As I tried to boot from the DVD, nothing happened, it froze pretty quickly with no useful messages.
Now I have installed Linux on the hdd using another computer. When I put the hdd back to my computer and try to boot, it freezes after showing the following messages:

ata8: hard resetting linkApparently there is some sort of incompatibility with the SATA controller of the motherboard. Is there any way to fix this? What should I try out?

I solved the problem by removing all drives from the ASMedia SATA ports that use the rogue ASM1061 controller.
Initially I had connected a DVD drive to the ASM1061 controller, but now I saw in the motherboard specs that these ports are only to be used with hard disk drives (see here footnote 4). I moved the DVD to a SATA Express port (also ASMedia), and now everything works. This is a bit strange, because according to the motherboard specs, this port is also only for hard drives. But it works for now, so I wont touch it.
Just for completeness: I got some useful tips from a relevant discussion in a debian forum:
