System: FreeBSD 5.1-CURRENT FreeBSD 5.1-CURRENT #2: Tue Oct 14 23:06:52 CEST 2003 toor at i386

	ASUS A7V-133
	AMD Athlon 1000 MHz
	SDRAM 133 MHz, 384 MB
	HD ad0 <ST380021A/3.75> ATA/ATAPI rev 5
	HD ad1 <ST380021A/3.19> ATA/ATAPI rev 5
	CD acd0 <CD-ROM Philips PCA403CDA/U31P> ATA/ATAPI rev 0

	-CURRENT repeatably fails to detect the ad1 device.
	atacontrol simply tells me "no device present".
	There are no error messages in dmesg, the system acts
	as if the disk was either missing or dead, which is isn't.

	Downdating sys/dev/ata/ata-lowlevel.c to rev 1.11 (I found
	someone doing that on freebsd-current) fixes the problem.
	I haven't yet tested if this is the last revision to work.

	I consider this a showstopper bug for 5.2-RELEASE.
