I have the same chipset and its even worse than the dell chipset
The solution is to plug in a external hdd trough usb so it wont use the sata chipset wich is cousing the problem.
Once at the instal select the real hdd (sata one)
If using a distro you could get a endless reboot busratio=20 will fix it most of the time.
The first boot with movie should be with cpus=2 if x2 or cpus=4 if x4
There you go amd hackintosh
