FreeBSD 4.9 RC1 (more bad news)

A few hours ago I downloaded .../i386/ISO-IMAGES/4.9-RC1-i386-disc1.iso
and made kern/mfsroot floppies from it.  If I enable my ICH5R SATA
controller in "native" mode, the 4.9-RC1 GENERIC kernel hangs solidly
(only the system reset button can unwedge it) during device configuration.
The last line of bootstrap monologue written by the kernel is:

	plip0" <PLIP network interface> on ppbus0

If I do a "boot -v", the kernel continues with:

	bpf: lp0 attached
	ed0: not probed (disabled)
	fe0: not probed (disabled)
	ie0: not probed (disabled)
	lnc0: not probed (disabled)
	cs0: not probed (disabled)
	sn0: not probed (disabled)
	isa-probe-children: probing PnP devices

before it hangs.  If I boot with the ICH5R SATA enabled in legacy mode,
the kernel does not hang.  It continues from this point with the output:

	BIOS Geometries:
	 0: 03fffe4f 0..1023=1024 cylinders, 0..254=255 heads, 1..63=63 sectors
	 1: ...

and so forth.  The system finishes booting and /stand/sysinstall starts.

I would guess that the bug is in the ata controller/disk driver.

The 4.9-20030914-PRERELEASE GENERIC kernel also hangs if the ICH5R SATA
controller is enabled in native mode, though not at the same point.
It wedges when the controller is first probed.
