Hi!

I'm having some problems burning CDs and DVDs with -current on a=20
new ASUS P5B-E board with an Intel Core 2 Duo. The IDE DVD drive, a Plextor=
=20
PX708A is connected to the JMicron JMB363 controller.

=46irst of all, there's a problem detecting the atapicam based cd0 device. =
As=20
long as hw.ata.atapi_dma is set to 1, the boot hangs while the kernel=20
searches for the device. Many commands time out like:

(probe0:ata4:0:0:0): xpt_schedule
(probe0:ata4:0:0:0): xpt_setup_ccb
(probe0:ata4:0:0:0): probestart
(probe0:ata4:0:0:0): xpt_action
(probe0:ata4:0:0:0): INQUIRY. CDB: 12 1 80 0 ff 0
atapi_action: hcb@0xc4a47c80: 12 1 80 0 ff 0
(noperiph:ata4:0:-1:-1): xpt_async
(noperiph:ata4:0:0:0): xpt_compile_path
(noperiph:ata4:0:0:0): xpt_release_path
acd0: FAILURE - INQUIRY timed out
atapi_cb: hcb@0xc4a47c80 sense =3D 00: sk =3D 0
acd0: cmd INQUIRY status 00 result 05 error 00
(probe0:ata4:0:0:0): xpt_done
(probe0:ata4:0:0:0): camisr
(probe0:ata4:0:0:0): probedone
(probe0:ata4:0:0:0): xpt_action
(probe0:ata4:0:0:0): INQUIRY. CDB: 12 1 80 0 ff 0
atapi_action: hcb@0xc4a47c40: 12 1 80 0 ff 0
acd0: WARNING - TEST_UNIT_READY taskqueue timeout - completing request=20
directly
(noperiph:ata4:0:-1:-1): xpt_async
(noperiph:ata4:0:0:0): xpt_compile_path
(noperiph:ata4:0:0:0): xpt_release_path
acd0: FAILURE - INQUIRY timed out
atapi_cb: hcb@0xc4a47c40 sense =3D 00: sk =3D 0
acd0: cmd INQUIRY status 00 result 05 error 00
(probe0:ata4:0:0:0): xpt_done

Nevertheless, after about 20 minutes both devices, an acd0 and a cd0 are=20
recognized. I can mount a CD using both acd0 and cd0 and reading from the C=
D=20
is no problem. But when I try to burn a CD or DVD with burncd or cdrecord,=
=20
after a while the drive's LED stops blinking and the process then hangs=20
indefinitly.

If I turn dma off (hw.ata.atapi_dma=3D"0" setting in loader.conf), the driv=
es=20
are correctly detected and there are no hangs (no timeouts) during boot.=20
Mounting and reading from the CD is no problem, but burning doesn't work=20
either :-(.

Any ideas?

Thanks in advance,
Christian.
