I'm trying to get the ACPI stuff working an my Acer Travelmate c100.
I've seen a couple of posts about this, but I'm not able to get it
working. I found the patch from John Turney at
http://sourceforge.net/mailarchive/forum.php?thread_id=3854113&forum_id=6102 and manually applied the changes to my kernel, but upon reboot with the new kernel, the system reboots very early in the boot process. I don't understand the kernel code well enough to do much hacking on it, so I was wondering if anyone had any good resources on getting this working. I'm using Fedora Core 2 with the updated kernel.

$ uname -a
Linux zen.localnet 2.6.8-1.521custom #6 Sat Aug 28 18:12:02 CDT 2004
i686 i686 i386 GNU/Linux

Any help is appreciated.

Thanks,

Russell

Where would I start to try and correct the ACPI problem. Apparently, the 2.6.x kernel will not enable the ACPI if there is an error. If I run dmesg, I get :

ACPI: RSDP (v000 Acer ) @
0x000ec2d0

The BIOS memory map looks like :

BIOS-provided physical RAM map:
BIOS-e820: 0000000000000000 - 000000000009fc00 (usable)

running acpidmp from pmtools gives me this :

RSDP "Acer" @ 0x000ec2d0
0000: 52 53 44 20 50 54 52 20 00 41 63 65 72 20 20 00 RSD PTR .Acer
.
0010: 00 00 00 00 ....

acpidmp: cannot map the RSDT

As stated in my first email, I tried manually applying the patch provided in that post. I say I manually applied it because all 3 hunks failed when I tried to use 'patch -p1'. I have some knowledge of programming, but I don't completely understand what the patch is trying to do and I don't know how to get debugging information from the kernel; especially since these changes to the kernel just cause it to reboot when it hits the ACPI init.

Any help is appreciated.

Thanks.
