Hi,

I'm using freebsd 3.4-RELEASE with CREATIVE CD-RW RW4224E:

/kernel: wdc1: unit 0 (atapi): <CREATIVE CD-RW RW4224E/1.36>, removable,
accel, dma, iordis
/kernel: acd0: drive speed 4125KB/sec, 1860KB cache
/kernel: acd0: supported read types: CD-R, CD-RW, CD-DA, packet track
/kernel: acd0: supported write types: CD-R, CD-RW, test write
/kernel: acd0: Audio: play, 255 volume levels
/kernel: acd0: Mechanism: ejectable tray
/kernel: acd0: Medium: no/blank disc inside, unlocked, lock protected

I was burning my cds using wormcontrol, it was working fine. But now I've
changed to 4.0-RELEASE and I'm having some problems. Some times the CDRW
is detected this way:

/kernel: ata1-master: timeout waiting for command=ef s=00 e=00
/kernel: acd0: CD-RW <CREATIVE CD-RW RW4224E> at ata1-master using BIOSPIO

some times this way:

/kernel: acd0: CD-RW <CREATIVE CD-RW RW4224E> at ata1-master using PIO4

And I'm losting several cds using burncd command, my drive freeze and only
work after power cicle. I get this mesage when the CDRW freeze:

/kernel: acd0: READ_TOC - ILLEGAL REQUEST asc=24 ascq=00 error=00
/kernel: acd0: WRITE_BIG - HARDWARE ERROR asc=09 ascq=01 error=00
/kernel: acd0: REQUEST_SENSE command timeout - resetting
/kernel: ata1: resetting devices ..  device dissapeared! 1 ata1-master:
timeout waiting to give command=ef s=90 e=20
/kernel: done
/kernel: ata1-master: timeout waiting to give command=a0 s=90 e=20
/kernel: acd0: failure to send ATAPI packet command
/kernel: acd0: failure to execute ATAPI packet command 

Is this problem solved in freebsd 4.0-STABLE? What is happening?

Thanks,
Paulo Fragoso.
