Hi.

I have a problem that 120GB IDE hard disk isn't recognized.  Here is
dmesg(8)'s output with first two line masked.

(It is intentional that Some USB devices aren't recognized and the
correct mii device isn't attached to wm(4).)

My colleague reported me that (old) FreeBSD 2.2.8 detect above hard
disk recognized normally and smaller size (40GB) hard disk had no
problem.

I tested with NetBSD current (1.6W) and got the same result with 1.6.1.

After testing some debug flags, I found that settting wdcdebug_mask to
DEBUG_FUNCS(0x08) change this situation, the drive is recognized.
It seems that there is some timing problem?

Any advise is welcome but I'm away from the machine until 12th Aug.
