Subject:   4.9-20030914-PRERELEASE hangs during boot

I just noticed the 4.9-20030914-PRERELEASE and made a set of
installation boot floppies from it to see which of the devices
in my new PC the PRERELEASE would support.

It wedged hard during the boot autoconfiguration monologue,
just after typing these lines on the console:

atapci0: <Intel ICH5 ATA100 controller> port 0xf000-0xf00f,0-0x3,0-0x7,0-0x3,0-0x7 irq 0 at device 31.1 on pci0
ata0: at 0x1f0 irq 14 on atapci0
ata1: at 0x170 irq 15 on atapci0
atapci1: <Generic PCI ATA controller> port 0xd000-0xd00f,0xcc00-0xcc03,0xc800-0xc807,0xc400-0xc403,0xc000-0xc007 irq 5 at device 31.2 on pci 0

I had to free it with the system reset button.

My motherboard is a Gigabyte 8KNXP which uses the Intel 875P/ICH5R
support chipset.  Device "atapci1" is the ICH5R serial ATA controller,
configured to operate in "native" mode.  When the 5.1-RELEASE generic
kernel reaches this point, it continues with "ata2" and "ata3" and
finishes booting.

The 4.9-20030914-PRERELEASE generic kernel wedged solid.  I tried to
boot it twice.  If I reconfigure the serial ATA controller to operate
in "legacy" mode (in which it pretends to be a standard parallel ATA
controller), the 4.9-20030914-PRERELEASE kernel boots correctly.

Another "operating system" that wedges solid when it sees the serial
ATA controller configured in native mode is Windows 98SE.  I am a
little shocked and disappointed that 4.9-20030914-PRERELEASE does
no better than Windows since I was planning on running 4.9-RELEASE
on my new PC.  (5.1-release is a little too flaky for prime time.)

It would be real nice if this could be fixed in the final release.
I bet there are a bunch of other FreeBSD users out there with new
motherboards using the 875P/ICH5R support chipset and some of them
also have serial ATA drives and would rather not configure the
serial ATA ports to operate in "legacy" mode (which renders one the
parallel ATA ports unusable).
