PROBLEM REMAINS: [sata_nv ADMA breaks ATAPI] Crash on accessing DVD-RAM

Hello!

The problem described at https://bugzilla.redhat.com/show_bug.cgi?id=351451 and
at http://ubuntuforums.org/showthread.php?t=655772 and supposedly fixed by the
patch http://kerneltrap.org/mailarchive/linux-kernel/2007/11/25/445094 is still
there. I have compiled 2.6.24-rc7 kernel and booted my PC with it just to find
out that my SATA DVD-RW is

sr0: scsi3-mmc drive: 0x/0x caddy

as it was before with 2.6.23.12 and earlier 2.6 kernels compiled for x86_64.
Trying to use sr0 after this results in dead hang or reboot.
When I put sata_nv.adma=0 or mem=4096M then it's all ok:

sr0: scsi3-mmc drive: 94x/94x writer dvd-ram cd/rw xa/form2 cdda tray

and DVD works normally.

My system has 4G of physical memory, but when I use mem=4096M kernel sees only
3406720k. It is obvious that when limiting memory by mem=4096M kernel doesn't
use the last range provided by BIOS:

Command line: BOOT_IMAGE=new ro root=805 mem=4096M 1
BIOS-provided physical RAM map:
BIOS-e820: 0000000000000000 - 000000000009f000 (usable)

Entering add_active_range(0, 0, 159) 0 entries of 256 used
Entering add_active_range(0, 256, 851680) 1 entries of 256 used
end_pfn_map = 1048576

I guess it is because of holes in between those ranges. And my SATA DVD-RW works
ok. But when I don't limit memory or limit it starting from mem=4098M and above,
my SATA DVD-RW is not detected correctly and does not work.

I noticed that when memory is not limited, the buffer pointed to by unsinged
char *buffer in function get_capabilites in driver sr.c contains all zeros
instead of some reasonable values when function scsi_mode_sense returns on the
line 766. This leads to

sr0: scsi3-mmc drive: 0x/0x caddy

and wrong device behavior.

By the way, there is no such problem with kernels compiled for x86_32.
