Hello,

I included a mail from the 'acpi4asus-user' mailing-list, as the problem
is already know and Andre Messerschmidt found a solution (at least to
see the battery IIRC).

I had the same problem on my M6800N. After changing the DSDT table I now
have
BAT0 and BAT1 but both are always absent, no matter what I do.
You can download my DSDT table from here
http://www.isis.de/members/~messersch/asus-m6800n.html
Maybe it helps.

I am not sure if this is a problem of the DSDT table or a bug in ACPI
itself.

best regards

As I wanted to use Andre's DSDT, I patched my 2.6.2 kernel with the
'ACPI DSDT in initrd' patch from http://gaugusch.at/kernel.shtml. The
latest patch available is against 2.6.1 and it applies with an hunk over
kernel 2.6.2 + ACPI 20040211 (no matter if I patch with the latest ACPI
before or after the 'ACPI DSDT in initrd' patch):

Then, I compiled Andre's DSDT with the latest 'iasl' from Intel:

I compiled kernel 2.6.2 with the 'ACPI DSDT in initrd' patch and I
prepared my LiLo tu use it: as I don't use any initrd, I copied Andre's
compiled DSDT in /boot/ and I added these lines to /etc/lilo.conf:
> 	image=/boot/vmlinuz-2.6.2-acpi-dsdt-initrd
> 	        label=262-dsdt
> 	        read-only
> 	        initrd=/boot/dsdt-m6842nwh_20040216.01.aml

At reboot, anyway, I can't see any line 'Looking for DSDT in intird',
but, strange, if now I grab my DSDT, this is Andre's one, not mine (as
if the DSDT was read from initrd). On the contrary, battery0 is still no
present (I attached my kern.log_20040217).

On the other hand, as from the syslog_20040216 I attached, during
various tests I made yesterday, just one time I could see the famous
'Looking for DSDT in initrd' in 'syslog', so IMHO now every boot the
kernel takes my customized DSDT. In fact, the latest kern.log_20040217
lacks some line which are present in syslog_20040216:

Now, the real problem is in these lines:

found customized DSDT with 22420 bytes!

/et-voilà/: the kernel reads my customized DSDT, but after it doesn't
used it (the 'replaced by host OS' message), so I've the corrected DSDT
in /proc/acpi/dsdt, but not used. Am I right? In fact, I get all the
errors I've with the original DSDT (which I'd like to correct, but after
having booted with the new DSDT).

Any ideas?

Thx, bye,
Gismo / Luca

PS to Andre Messerschmidt: I don't know if you're subscribed to
'acpi-devel', so I cc you.

PPS to Markus Gaugusch: I think your patch (version for 2.6.1 vanilla)
is applicable even on 2.6.2, while there's just an hunk.
