On FreeBSD 8.1-release, I was unable to load ahci without causing a system panic. Since recently going to FreeBSD 8.1-STABLE #0: Fri Nov 19 12:17:12 MST, I have been able to boot with ahci loaded as a module but it leaves my two mirrored root-on-zfs main drives as ad devices while attaching to my three gvinum controlled drives so they become ada devices. I tried recompiling my -stable kernel to make ahci take over the disks but found the system goes back to a panic state on boot until I remove loading gvinum from /boot/loader.conf, at which point all disks attach as ada devices. The kernel configuration changes are: --- /usr/src/sys/amd64/conf/GENERIC 2010-10-25 00:58:37.000000000 -0700 +++ /root/kernels/MYKERNEL8 2010-11-19 12:10:37.362055289 -0700 @@ -95,11 +95,12 @@ # ATA and ATAPI devices device ata -device atadisk # ATA disk drives -device ataraid # ATA RAID drives +device ahci +#device atadisk # ATA disk drives +#device ataraid # ATA RAID drives device atapicd # ATAPI CDROM drives -device atapifd # ATAPI floppy drives -device atapist # ATAPI tape drives +#device atapifd # ATAPI floppy drives +#device atapist # ATAPI tape drives options ATA_STATIC_ID # Static device numbering # SCSI Controllers and the panic as best as I could get from a camcorder recording of my screen is: GEOM: new disk ada4 GEOM: ada0s2: geometry does not match label (255,63s != 16h,63s).

I have not been able to get a dump from the panics (which is likely my bad in some way). Maybe I can yank out one of the two 2GB sticks of ram and setup my flash drive as a swap device, but will it be available soon enough? The motherboard doesnt have a serial port connector, but I think there is a header to attach one. If useful, I can look into linking it to my dad's old computer's serial port that way.
