This sounds suspiciously like a problem that has cropped up in CURRENT
with ATAng. It looks like an interrupt is lost on resume. If I have a
single disk on the system, it hangs resetting that disk. If I have two
disks, it hangs on the second one. Either way, it never returns from
suspend.

On CURRENT, this only seems to show up with ACPI, but I don't think you
are using ACPI on your system from the dmesg.
