[gentoo-user] cannot burn dvd

[Andrey Vul]

cdrecord (2.01.01a53) hangs when trying to write to a SATA dvd drive
using libsg. When I set SATA mode in BIOS to Compatability, the
burning works but somehow the 8x speed is reduced to 1x.

Chipset: Intel ICH9M (AHCI)
DVD Burner: Hitachi-LG DVD-Multi mini-SATA

None of the google links helped me.

Try ts=63k 
It may be that the Linux kernel has a problem with biger DMA sizes.
I am going to go back to this as default after it turns out that only
FreeBSD is able to handle biger sizes correctly.

Well, nvidia has a binary blob for FreeBSD and if iwl5000 is
supported, bye-bye Linux, hello FreeBSD!

That didn't help, and I still get the error. At least now it shows the
ata exception that can be found in dmesg logs from googling "cdrecord
ahci sata". It looks like a controller timeout (this has happened
before, causing DMAR error lines in dmesg). Is it worth disabling AHCI
or not? And should this be also asked on lkml because this looks like
a controller/driver/ahci issue? I don't want to contribute to the
information overload between the [PATCH X/Y] foo and other messages.
