AtapiCam Failing on CD Burner

[Jason Cox]

Hello all,

Whilew trying to get CD burning working under FreeBSD 6.0 (and
6.1-PreRelease), I keep getting the following error in my dmesg and cd1
is never created. The drive is a Philips CDRW4012P. It shows up
as /dev/acd1 and reports correctly in dmesg. However, once atapicam
tries to query it, it just repeats the follwoing (output from dmesg with
boot -v):

ata1: reiniting channel ..
ata1: reset tp1 mask=03 ostat0=50 ostat1=00
ata1: stat0=0x00 err=0x01 lsb=0x14 msb=0xeb
ata1: stat1=0x00 err=0x01 lsb=0x14 msb=0xeb
ata1: reset tp2 stat0=00 stat1=00 devices=0xc<ATAPI_SLAVE,ATAPI_MASTER>
acd0: setting PIO4 on ICH5 chip
acd0: setting UDMA33 on ICH5 chip

I have looked all over the internet and everywhere says it should have
been fixed in 4.7. Any advice on what else to try?
