I am having a similar problem when I set up my Virtual Machines to use EITHER Virtual SATA or SAS controllers. With SATA, I'm getting the same errors posted above I tried disabling NCQ on my Linux guest and that did not help. The problem occurrs when I try to
READ data over the network connection. Writing isn't a problem up to 20 MB/sec or more. But reading 4 MB/sec from a video editing program (I test these) kills my Linux VM every time. And, of course, OS X crashes when anything goes wrong on a network connection!
When I reconfigured my VM to use SAS (I installed the LSI mptsas drivers on my Linux guest), I am getting a similar issue. The VM disk system just dies with a different message:

I don't have these problems with the exact same Linux guest and VMware, whether I emulate IDE or SAS disks (SAS with the same LSI mptsas driver)
Guest: My Linux distro is Mandriva 2010 64-bit but I'm running my own 2.6.32.11 kernel.
Host: OS X 10.6.4 or Windows 7 64-bit, 4 GB RAM, 7200 RPM OS Drive on a laptop
VirtualBox Version 3.2.8
Very discouraging!!!
