Hi,
I'm having trouble with the isci driver in both stable and current. I
see the following dmesg in stable:
isci0: <Intel(R) C600 Series Chipset SAS Controller (SATA mode)> port
0x5000-0x50ff mem 0xe7afc000-0xe7afffff,0xe7400000-0xe77fffff irq 19
at device 0.0 on pci11
isci: 1:000051 ISCI bus_alloc_resource failed
I'm running FreeBSD on VMWare ESXi 6 with vt-d passthrough of the isci
devices, here is the relevant pciconf output:

ecap 000e[138] = ARI 1
ecap 0017[180] = TPH Requester 1
ecap 0010[140] = SRIOV 1
I haven't tried booting on bare metal but running a linux distro
(centos 7) in the same VM works without issue. Is is possible the
SRIOV option is causing trouble? I don't see a BIOS option to disable
that setting on this server like I have on some others. Any other
ideas to get this working?
Thanks,
Brad
