The following reply was made to PR kern/103602; it has been noted by GNATS. From: "Josh Carroll" <josh.carroll@psualum.com> To: "Thomas Quinot" <thomas@freebsd.org>, FreeBSD-gnats-submit@freebsd.org Cc: greg@rowes.org, Tadas <haitti@gmail.com> Subject: Re: kern/103602: atapi device not working on JMicron 363 Controller Date: Sat, 14 Oct 2006 19:53:22 -0700 Hi Thomas, Just a bit of extra information. I disabled the ICH8 controller entirely in the BIOS, and booted with a 6.1-RELEASE kernel. The box still hangs up with atapicam loaded and I can't read files from a udf-mounted DVD with or without atapicam. I'm also copying another user on this since he's having similar problems with the Asus P5B Deluxe.

The system is a new Core 2 Duo system with an Asus P5B motherboard. I have tried two different Intel P965 chipset based boards with the same problem (Asus P5B Deluxe, Gigabyte DS3). I have tried 2 other DVD devices and an old 50x CD drive. I've replaced cables, tried the device on the controller by itself, and even tried a 3rd party PCI PATA IDE controller. None of the above fixes the problem. > > This report is not completely clear to me. Do you get the same problem > if you use the same DVD drive on a different controller?

I was able to mount a CD disc and copy files, but I do get the same error for larger files on a couple of CDs. I am using a custom kernel config, but with only a few additions from GENERIC/SMP. And the same problem occurs with the GENERIC/SMP kernels. If I load atapicam, I see in dmesg: > > > > ata4: reiniting channel .. > > ata4: reset tp1 mask=03 ostat0=50 ostat1=51 > > ata4: stat0=0xd0 err=0xd0 lsb=0xd0 msb=0xd0 > > ata4: stat0=0xd0 err=0xd0 lsb=0xd0 msb=0xd0 > > ata4: stat0=0x50 err=0x01 lsb=0x00 msb=0x00 > > ata4: stat1=0x00 err=0x01 lsb=0x14 msb=0xeb > > ata4: reset tp2 stat0=50 stat1=00 devices=0x9<ATAPI_SLAVE,ATA_MASTER> > > ata4: reinit done .. > > > > Any attempt to mount/touch the device at this point hangs the process.

Attempt to mount the DVD and copy one of the larger .VOB files.
