Hi,
I just upgraded a few machines from 8.2-STABLE (r221983) to 9.0-STABLE
(r234600) and now they can't find any disk because SAS controller cannot
initialize with the following diagnostic:
mpt0:<LSILogic SAS/SATA Adapter> port 0xd000-0xd0ff irq 26 at device
3.0 on pci6
mpt0: 0x4000 bytes of rid 0x14 res 3 failed (0, 0xffffffffffffffff).
mpt0: Unable to memory map registers.
mpt0: Giving Up.
pciconf -lv:
mpt0@pci0:6:3:0: class=0x010000 card=0x81dd1043 chip=0x00541000 rev=0x02
hdr=0x00
vendor = 'LSI Logic / Symbios Logic'
device = 'SAS1068 PCI-X Fusion-MPT SAS'
class = mass storage
subclass = SCSI
I tried to boot to latest HEAD and found the same problem. I also tried
to build kernel with mpt driver from my 8.2. Controller didn't
initialize with the same diagnostic. So it looks like the problem is not
in mpt driver.
Any help would be appreciated.

Hi John,
Could you please help me with the problem above? It looks like the
problem is in PCI code and you changed things there.
Can you get a verbose dmesg?
Yes, it's in attach.
Can you get the output of 'devinfo -u' and 'devinfo -rv' from a broken kernel?
Attached.
Can you also try setting 'debug.acpi.disable=sysres' in the loader?
Didn't help.
