5.3 BETA kernel hangs without debugging options

I have been trying to track down a problem with the 5.3 BETA4 kernel
where it would hang after trying to sense my CD ROM drive.  I have
found that disconnecting the CD ROM drive would allow it to boot the
kernel.

Durring my trouble shooting, I tried different version of the 6.x ata
driver on the 5.3-BETA4 kernel without any luck in getting it working.

NOTE: I have had to use the 6.x ata driver on my previous 5.3-BETA
kernels due to problems with crashes when detecting my CD-ROM drive
with the 5.3 ata driver.  I kept the ata driver the same (6.x
08272004) thru-out all kernel builds to eliminate it as a suspect.

So far I have isolated the problem to the commit that removed the
debugging options from the 5.3 BETA GENERIC kernel.

# ident /sys/i386/conf/GENERIC
$FreeBSD: src/sys/i386/conf/GENERIC,v 1.413.2.1 2004/09/07 23:49:57 scottl Exp $

The kernel without the debugging options would get to here and hang:

ATAPI_RESET time = 390us
ad0: 26105MB <WDC WD273BA/P78OA30A> [53040/16/63] at ata0-master BIOSPIO
acd0: WARNING - MODE_SENSE_BIG interrupt was seen but taskqueue stalled

I'm currently building a 5.3 BETA4 kernel with the debuging options enabled.

Any hints as to how I should proceed from here?

The full dmesg from a kernel with the debugging options enabled is below:
