Hi, I reported this several weeks ago. It is still occurring with kernels built today (last night's CTM bucket, CST [UTC -0600]). We removed a CDROM-only drive and replaced it with a newer 'Combo' model from the same company (LG). Immediately we saw the repeated lines as shown in the longer dmesg below. This newer drive has latest firmware available on LG's site. After FBSD comes up, the newer drive seems to be quite usable, albeit we may see known problems in apps such as burncd. The older CDROM-only drive had latest firmware, too, but it did not produce the stat line(s) at all: [...] ata1-master: pio=0x0c wdma=0x22 udma=0xffffffff cable=40pin ata1-master: setting PIO4 on Intel PIIX4 chip ata1-master: setting WDMA2 on Intel PIIX4 chip acd0: <CRD-8322B/1.12> CDROM drive at ata1 as master acd0: read 5500KB/s (5500KB/s), 128KB buffer, WDMA2 acd0: Reads: CDR, CDRW, CDDA stream, packet acd0: Writes: acd0: Audio: play, 255 volume levels acd0: Mechanism: ejectable tray, unlocked, lock protected acd0: Medium: CD-RW 120mm photo disc [...] I've quadruple-checked the jumpers and they are correct. There is no slave unit on any ATA channel at all; in fact IBM's ribbon cables have no extra connectors. :-( Changing the sysctls for ata/dma have no effect. IBM's SurePath BIOS is the latest I can find, and changing the 'high-performance:compatible' setting for the CD drive has no effect. There's not much else to mess with, there.
