Thanks Jerry, We have determined that our problem is related to the god-awful mess known as ACPI. With a single processor installed, it all boots fine, including finding PCI busses 1 and 2 .... and the raid on the aac driver is peachy! With 2 or more processors installed, and ACPI enabled, it panics with a madt error about id 38 is greater than the allowed max And with ACPI disabled, it boots, but doesnt find PCI busses 1 and 2, which is unfortunate as the RAID controller sits in PCI bus 1 .... and the bge inet interface seems to be on PCI bus 2 ....=20 So at present we are on the FC6 path, which is obviously much softer on the vagaries of ACPI and is ignoring the crap data returns. mjt > -----Original Message----- > From: Jerry McAllister [mailto:jerrymc@msu.edu]=20 > Sent: Friday, 20 April 2007 12:40 AM > To: Murray Taylor > Cc: FreeBSD Mailing List; freebsd-hackers@freebsd.org > Subject: Re: IBM / FreeBSD Install problem >=20 > On Thu, Apr 19, 2007 at 10:14:13AM +1000, Murray Taylor wrote: >=20 > > Server: IBM X3850 (88633SM) > > CPU X 4: 40K2522 > > HDD X 6: 40K1051 > > IBM ServeRAID 8i: 39R8729 > >=20 > > We are attempting to install FreeBSD 6.2-RELEASE onto this=20 > machine and > > are running into a problem getting the operating system to=20 > recognise the > > RAID controller.
