If it's not already apparent. The board has an AMD 880G chipset, that provides RAID support on 6 ports @ 6GBs. Now, from a purely logistical standpoint. The numbers _can't_ be meaningless. It's clear that the kernel is making a "judgment call" here: kernel: ad6: setting UDMA100 The "judgment call" on both GENERIC/i386, and GENERIC/amd64 was never made. The capability of both the port && the drive were accepted. Both cases were booted using "verbose" (5). Please understand, I'm not attempting to be argumentative here. I just observe this to be true. In other words; it must have _some_ meaning - no?
