| |
AHCI pauses heartily on during detection boot, but eventually proceeds. This problem currently exists with 2.6.19-rc2-mm1, but did not exist in 2.6.17.3. I realize that's a huge gap, and if you'd like me to narrow it down, I'll be glad to try.
Messages surrounding the hang:

I should note that on this system ata1 and ata3 both detect quickly, but they have 1.5 Gbps devices whereas ata2 has a 3.0Gbps device.
