Please see below for a description of my problem, which I had written
about to SuperMicro support. Further to what I've written there, I
have modified the ahci driver source to force HOST_CAP_PMP as in the
diff included below. Now when this modified driver is loaded, it does
attempt PMP, and it appears to be working except the all but the first
drive attached to the port multiplier are not recognized. I've included
relevant syslog entries below.
Any advice as to what I can try next?
Thanks,
Todd

Despite the appearance of partial success in my syslog messages below (ie.
PMP appeared to sorta kinda be trying to work, almost), I've since read
some more that leads me to believe that Intel ICH10 does not support PMP.
And Intel authoritatively says so here:
http://www.intel.com/Assets/PDF/datasheet/319973.pdf
page 538, section 14.4.1.1, Bit 17
Supports Port Multiplier (PMS) - R/WO. ICH10 does not support port
multiplier.
NOTE: This bit must be set to 0. Port multiplier is not supported by
ICH10.
So, I give up. I edited the wiki page here accordingly since it was
wrong:
