OK, I took a chance and flashed the card's BIOS to the latest from the AMI
site.... I had been suspecting BIOS, as the readme.txt mentioned problems
with newer motherboards. Lo and Behold, it seems to have done the trick
amr0: <AMI MegaRAID> mem 0xe9000000-0xe93fffff irq 11 at device 12.1 on pci0
amr0: firmware GH6D bios 1.43 32MB memory
amrd0: <MegaRAID logical drive> on amr0
amrd0: 17522MB (35885056 sectors) RAID 5 (optimal)
As I mentioned, the card came as a Dell unit. I tried the latest BIOS from
Dell, but that was a year old. The BIOS from megaraid.com 1.43, which is
in there now *seems* to work so far.... At least I can now get a disklable
on the drive and newfs the drive
