   I have some regression (or anti-regression?) with ATA on my
home system (RELENG_5 from last Friday)
I have had bad IDE 80-conductor cable, so I temporary switched
two my ATA devices with old 40-conductor cable on the secondary IDE
Now I have something strange: my SAMSUNG SP0411N HDD on the secondary IDE
channel detected again as UDMA100 device, but works with errors (as expected
anyway in this situation).
ATA controller on my system (from dmesg output):
atapci0: <VIA 82C686B UDMA100 controller> port 0xd000-0xd00f,0x376,0x170-0x177,0x3f6,0x1f0-0x1f7 at device 7.1 on pci0
and my devices:
ad0: 19130MB <SAMSUNG SV2001H/QN200-05> [38869/16/63] at ata0-master UDMA100
ad1: 38166MB <ST340016A/7.18> [77545/16/63] at ata0-slave UDMA100
acd0: CDROM <SAMSUNG CD-ROM SC-152L/C100> at ata1-master PIO4
ad3: 38204MB <SAMSUNG SP0411N/TW100-11> [77622/16/63] at ata1-slave UDMA100
ad3: WARNING - READ_DMA UDMA ICRC error (retrying request) LBA=63
ad3: WARNING - READ_DMA UDMA ICRC error (retrying request) LBA=63

	So: where is my UDMA33 or PIO4? :)
