BTX halted on Proliant DL320 Gen8 v2's - fakeRAID support?

[Karl Pielorz]

Hi,

On our HP DL320 Gen8 v2's - BTX halts if we try to boot with the onboard 
SATA controller set to 'B120i RAID' mode, and have drives present (output 
from BTX is below).

If you boot with *no drives* present - it works, and does show from pciconf 
-lv:

ahci0 at pci0:0:31:2: class=0x010400 card=0x00841590 chip=0x8c048086 rev=0x04
hdr=0x00
  vendor    = 'Intel Corporation'
  device    = 'Lynx Point SATA Controller 1 [RAID mode]'
  subclass  = RAID

But with drives present BTX dies on 9.x, 10.x and a recent 11.x snapshot.

Is this controller supported in 'raid' mode? - i.e. if it got past BTX 
would it be usable?
