I am running -current and since a few days ago (at least 2011/04/11) I am unable to boot.
The boot process stops when it looks to find a bootable device. The prompt (when pressing '?') does not display any device and yielding one second (or more) to the kernel (by pressing '.') does not improve the situation.
A known working date is 2011/02/20.
I am running amd64 on a nVidia MCP51 chipset.
MCP51... again...
I am willing to help any way I can.
You could start from capturing and showing verbose dmesg. Full or at least in parts related to disks.
I captured the dmesg output for both the old (working) kernel and the new (bad) kernel. See attached for the difference between the two. If you need the full dmesg please let me know.
One thing I found is that the old kernel would not boot if I simply rebooted from the bad kernel. I had to do a hard power off before the old kernel would work again. Is some device state surviving between reboots?

As soon as all devices detected but not responding to commands, I would suppose that there is something wrong with ATA interrupts. There is a long chain of interrupt problems in this chipset. I have already tried to debug one case where ATA wasn't generating interrupts at all. Unfortunately, without success -- requests were executing, but not generating interrupts, it wasn't looked like ATA driver problem.
What's about possible candidate to revision triggering your problem, I would look on this message: +pcib0: Enabling MSI window for HyperTransport slave at pci0:0:9:0
At least it is recent (SVN revs 219737,219740 on 2011-03-18 by jhb) and it is interrupt related.
Does the driver disable MSI for MCP51? I think jhb's patch fixed one MSI issue of all MCP chipset.
