>Description:
the 5.2-CURRENT code in src/sys/dev/ata/ata-lowlevel.c does not recognize my 2x Sony CD-ROM on ata1.
The following dump is from dmesg bootverbose=yes before my patch:
..
atapci0: <Intel PIIX4 UDMA33 controller> port 0xb800-0xb80f,0x376,0x170-0x177,0x3f6,0x1f0-0x1f7 at device 4.1 on pci0

As you can see ata0 is correctly and quickly recognized, while ata1 is not. I think there is another problem with "stat=0x50 err=0x50 lsb=0x50 msb=0x50" because I have no more CD-ROMs attached, but I don't know how to fix it.
>How-To-Repeat:
>Fix:
This patch solves the immediate problem, and in fact it works for me (now I can see my CD-ROM), but I am new to FreeBSD and also I don't know whether this is a correct solution or not: here I simply assume that when err == 0 then it simply means no errors.
