Hardware: PC Asus / Athlon processor
OS : FreeBSD 4.7, GENERIC kernel

During the boot, I read in syslog messages:
        ata1-slave: ATAPI identify retries exceeded
        ad0: 19546MB <FUJITSU MPG3204AH E> [39714/16/63] at ata0-master UDMA100
        acd0: CD-RW <YAMAHA CRW2200E> at ata1-master PIO4
So the hard drive is primary master, the CD is secondary master.

The CD works since I can mount data CD. It works under Linux
with cdrecord.

I can write CD-RW with:
        burncd -f /dev/acd0c blank
        burncd -f /dev/acd0c data MY_ISO_IMAGE fixate
But with a CD-R the same (second) command fails and /var/log/messages says:

Nov 15 14:56:58 tempo2 /kernel: acd0: SEND_OPC_INFO command timeout - resetting 
Nov 15 14:56:58 tempo2 /kernel: ata1: resetting devices .. ata1-slave: ATAPI identify 
retries exceeded
Nov 15 14:56:58 tempo2 /kernel: done

Just once; what's about "ATAPI identify retries exceeded'? There's
nothing slave! Than, with a loop:

Nov 15 14:57:56 tempo2 /kernel: acd0: SEND_OPC_INFO command timeout - resetting 
Nov 15 14:57:56 tempo2 /kernel: ata1: resetting devices .. done
Nov 15 14:59:13 tempo2 /kernel: acd0: SEND_OPC_INFO command timeout - resetting
Nov 15 14:59:13 tempo2 /kernel: ata1: resetting devices .. done

Any hint? Thanks in advance,
