I'm happy to confirm that ESXi 5.5U2 doesn't prevent the Lynx Point AHCI Controller (as found on haswell based mainboars with the Intel C226 Chipset) to be used as PCI passthrough device anymore!

Just add it's chip ID to /etc/vmware/passthru.map, like ScottMerrilees mentioned in post #17, so a patch would look like

Tested under FreeBSD 10.1 guest OS (amd64), with single vector MSI, working as expected (less than 100MHz for 2500irqs/s@ahci0):

Hopefully DirectPath I/O is on par with 5.1 again :slightly_smiling_face:
