When booting with the Adaptec AAA-133 installed the kernel will crash when the first of three SCSI buses is probed. Each bus uses a AIC7880P to drive it. If the AIC driver is enabled in the kernel and not the AHC the kernel will not crash but the device shows up as an unknown PCI device.

This card was working with 4.1-Stable but when I upgraded to 4.1.1-stable this card stopped working in the present machine and in a test 4.1.1 machine but worked fine in a stock 4.0 install on the test machine. I have noticed that gibbs@freebsd.com has been working on the AIC and AHC code in the last nine days and is in the write time frame for this to be related The crash in either case looks like this copied from the machine screen: ahc0: <Adaptec aic7810 RAID memory controller> port 0xc800-0xc8ff mem 0xe6000000-0xe61ffffff,0xde000000-dxe000fff irq 10 ate device 0.0 n pci2 RAID Functionalality unsupported Fatal trap 12: pagefualt while in kernel mode fault virual address =0x32 fault code =superviso read, page not found instruction pointer =0x8_0xc013805b stack pointer =0x10_:0xc039fde4 frame pointer =0x10_:0xc039fdec code segment =base 0x0, limit 0xfffff, type 0x1b =DPL 0, pres 1, def32 1, gran 1 processor eflags =interrupt enable, resume, IOPL = 0 current process =0 (swapper) interrupt mask =net tty bio cam trap number =12 panic: page fault Uptime: 0s Full dmessage >How-To-Repeat: Install a AAA-133 on a PCI machine and boot with the AHC drive or without it and no AIC driver. >Fix: remove card or boot with the aic driver and no ahc driver.
