Hi everybody.

I've just bought and installed a LG GGW-H20L Blu-Ray burner,...
This is an SATA device, I'm running a 2.6.23.10 kernel (not the Debian
version) on Debian sid (AMD64) and I use the proprietary nvidia drivers
(169.07).
The system is an Dual (!) DualCore AMD Opteron machine.
(Please ask if you need further information)

The kernel seems to correctly identify the device (part of dmesg):

Anyway,... as soon as I insert an BluRay disc or an DVD my system
crashes (it either freezes, that happened with the DVD-R, or it reboots,
that happened with the BluRay disc).

There are no panics, oopses, or any other messages in the usual logs (at
least I didn't recognize them ;) ).

Any ideas?

Thanks and best wishes,
Chris.

btw: I'm cross posting this to lkml and debian-user,... hope nobody
feels offended :-)

How much RAM is in your machine? There's a known problem with sata_nv ADMA with ATAPI devices and over 4GB of RAM. As a temporary workaround, you can boot with sata_nv.adma=0 on the kernel command line, or limit your memory with the mem= command line option so that memory over 4GB is not used.
