freebsd stable - Sep 2006 - Problem with AHC after updating from 4.11 to 6.1 on the same server hardware

Hello!

After updating from 4.11 to 6.1-RELEASE-p3 I have the following problem with 
the Adaptec SCSI controller:

ahc0: <Adaptec 29160N Ultra160 SCSI adapter> port 0x1000-0x10ff mem 
0xfc510000-0xfc510fff irq 16 at device 4.0 on pci5
ahc0: can't allocate register resources
device_attach: ahc0 attach returned 12

No SCSI device will be detected. Has anybody experienced a similar problem 
with 6.1? Have tried to disable APIC and ACPI without success.

Not that it will help you, but I'm running 6.2-PRERELEASE compiled 9/23
with three Adaptec controllers and no problems; none of them is a 29160, 
however.

ahc0: <Adaptec aic7896/97 Ultra2 SCSI adapter> port 0xe000-0xe0ff mem 
0xfebfd000
-0xfebfdfff irq 16 at device 14.0 on pci0
ahc0: [GIANT-LOCKED]
ahc1: <Adaptec aic7896/97 Ultra2 SCSI adapter> port 0xe400-0xe4ff mem 
0xfebfe000
-0xfebfefff irq 16 at device 14.1 on pci0
ahc1: [GIANT-LOCKED]
ahc2: <Adaptec 2944 Ultra SCSI adapter> port 0xee00-0xeeff mem 
0xfebfc000-0xfebf
cfff irq 18 at device 18.0 on pci0
ahc2: [GIANT-LOCKED]
ahc3: <Adaptec 2940 Ultra SCSI adapter> port 0xed00-0xedff mem 
0xfebfb000-0xfebf
bfff irq 19 at device 20.0 on pci0
ahc3: [GIANT-LOCKED]

The motherboard is a Supermicro P6DGH with an onboard 78XX Adaptec 
controller, plus 2940 and 2944 (HV diff) for controlling two tape 
changers.

I have a 39160 in another system running 4.11; I'll try booting that under 
6.1 and see what happens.
