Hello,
I have a Supermicro A2SDi-2C-HLN4F with:
ahci0@pci0:0:19:0: class=0x010601 rev=0x11 hdr=0x00 vendor=0x8086
device=0x19b2 subvendor=0x15d9 subdevice=0x0969
vendor = 'Intel Corporation'
device = 'Atom Processor C3000 Series SATA Controller 0'
class = mass storage
subclass = SATA
and 4xTOSHIBA HDWG480 (N300) in a raidz2 and randomly I got tons of:
Dec 2 11:52:24 srv kernel: ahcich3: Timeout on slot 28 port 0
Dec 2 11:52:24 srv kernel: ahcich3: is 00000000 cs 10000000 ss 00000000 rs

I added hint.ahci.0.msi="0" to /boot/device.hints and since then problem no
longer occurred.
