I am not aware of any known but not resolved issues in this context.
But I think that I gave you a good advice.

Sorry about that, forgot to tell you about google.
Now, apologies about the joke, no offense meant :-)
These links should give a good overview for the start:
http://wiki.freebsd.org/DTrace
http://wiki.freebsd.org/DTrace/Examples
http://www.freebsd.org/doc/handbook/dtrace.html
http://wikis.sun.com/display/DTrace/Documentation
And, oh, here is a script that I used to investigate a somewhat similar problem
with failing ioctl. I think you should be able to easily adapt it to your
needs.
syscall::ioctl:entry
/execname == "k3b" && arg1 == 3299349762/
{
self->trace = 1;
}
fbt:::entry
/self->trace/
{
}
fbt:::return
/self->trace/
{
printf("%d", arg1);
}
syscall::ioctl:return
{
self->trace = 0;
}

Not sure if debugging with CAMDEBUG would be easier or not.
There could be lots of output.

Re: Difficulty playing DVDs under AHCI/CAM?
Just want to draw attention of those who use ahci, have hald running and burn optical media to couple of known issues: 1. http://thread.gmane.org/gmane.os.freebsd.devel.gnome/29636/focus=29652 2. http://thread.gmane.org/gmane.os.freebsd.devel.scsi/5128 3. k3b (and k3b-kde4) has a bug in its internal code which results in incorrect SCSI command(s) that may confuse some drive models at device or media probing stage. -- Andriy Gapon ___ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"

But I can read data DVD with ahci and sucessfully verify data with diff. While I have not had time to narrow it down, I have also had problems with burning DVD+R on my drive (LITE-ON DVDRW LH-20A1S 9L09) with the ahci driver on 8-STABLE using cdrecord. However, CD-RW's and DVD+RW's are not a problem. At the beginning of a failed burn, it seems like there is a short pause near the beginning (maybe after a block or two has been written, but I do not recall). If I find time, I will try again to burn a disc along with collecting all the debugging information I can. One thing I need to try, and you may too, is to see if there are any firmware updates for the drive. I see there is one for mine which I will try. Unfortunately, it does not say on the site what it improves unless the "Match more media" is it.

Difficulty playing DVDs under AHCI/CAM?
After a recent upgrade, I switched to AHCI/CAM for my SATA devices,
including a new DVD drive. Now I find that nothing can play DVDs any
more. For example, here's what mplayer does:

Same results (but without error messages) in vlc. My drive is
