sata_nv ADMA breaks ATAPI 4Gof RAM (AMD64?) and Which kernel will Lenny likely use when it is released?

[Karl Schmidt <karl@xtronics.com>]

Please reply off-list

If you try to mount a SATA DVD or CDROM and have more than 4G on a amd64 system:

$mount cdrom
mount: wrong fs type, bad option, bad superblock on /dev/scd0,
       missing codepage or helper program, or other error
       In some cases useful info is found in syslog - try
       dmesg | tail  or so

$ tail syslog
Jun 12 14:30:17 singapore kernel: UDF-fs: No VRS found

But these error messages are a bit misleading - see the links below


I would think that they would fix the 2.6.24 4G bug if that is what they will release with, but from 
what I read that isn't going to happen?

Seems like it would be a bad idea to release with a kernel that prevents mounting the CDrom if you 
have 4G of memory.

I can't find this bug listed in debian for linux-image-2.6.24-1-amd64, but I'm not sure that is the 
right place for it.

There is a patch around #55
https://bugzilla.redhat.com/show_bug.cgi?id=351451

I'm thinking of pulling in 2.6.25 from unstable for my machine running lenny, but don't want to 
create other problems once it goes stable.

How can I find the ETA of 2.6.25 entering lenny? (I think some of lenny is already frozen - would
that include the linux-image? (it isn't on the frozen list?)).
