RELENG_5 ATA lockup

[Barry]

I just cvsup'd from the BETA7 distribution to the latest source, and now
when I boot, I get the following two lines (which I had been getting
before) only now, my system hangs at this point during the boot.  Before,
I would get these two lines, followed by a line regarding the ATA reset
time.

I am using an Intel dual Xeon server class motherboard, the SE7501HG2.

I tried the patch that Soren posted yesterday, but it did not help.  Let
me know if there is anything I can do to help resolve this bug.
