I have problem with an ASUS DRW-1609P with both 5.3 and 5.4.  It won't
write any media.  Even "burncd" fails with the following error:

(Yes, I know I have "test" mode on, I got tired of making coasters)
> burncd -f /dev/acd0 -s max -v -t data file.iso  fixate
> adding type 0x08 file mp3.iso.aa size 720000 KB 360000 blocks
> next writeable LBA 2136
> addr = 2136 size = 737280000 blocks = 360000
> writing from file mp3.iso.aa size 720000 KB
> written this track 1120 KB (0%) total 1120 KB
> only wrote -1 of 32768 bytes: Device busy

Relevent line from dmesg:

acd0: DVDR <ASUS DRW-1608P/1.17> at ata1-master PIO4

atapicam doesn't fix it.  UDMA doesn't fix it.  GENERIC kernel.

Reading works fine.

Suggestions?
