I just got a new usb 8-in-1 media reader and when it is plugged into my
motherboard, my boot cycle hangs at:

npx0: [FAST]
npx0: <math processor> on motherboard
npx0: INT 16 interface
acpi0: <A M I OEMXSDT> on motherboard

Normally, a:

acpi0: Power Button (fixed)
Timecounter "ACPI-fast" frequency 3579545 Hz quality 1000

would come next, however it's completely hung.

I can plug the device into my motherboard after boot (once i've
booted without it) and it seems to work fine until I need to reboot and
then it hangs again.

'camcontrol devilist' shows 4 lines for it:

<USB2.0 SMARTMEDIA/XD \000\000\000?>  at scbus1 target 0 lun 0
(da0,pass0)

<USB2.0 CompactFlashCard \000\000\000?>  at scbus1 target 0
lun 1 (da1,pass1)

<USB2.0 SD/MMC     card \000\000\000?>  at scbus1
target 0 lun 2 (da2,pass2)

<USB2.0 MemoryStick Card \000\000\000?>  at
scbus1 target 0 lun 3 (da3,pass3) 

'acpidump -t -d' gives me :

"acpidump: RSDT entry 2 (sig OEMB) is corrupt"

among an otherwise normal looking dump.

I have a ASUS p4p800 deluxe motherboard running 5.3-RELEASE-p2 on an HT
P4.
My usb controller dmesg lines look like:
Intel 82801EB (ICH5) USB controller USB-A

What other debugging steps do I need to perform for this?
