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 >>> ERROR: Invalid checksum The BIOS memory map looks like : BIOS-provided physical RAM map: BIOS-e820: 0000000000000000 - 000000000009fc00 (usable) BIOS-e820: 000000000009fc00 - 00000000000a0000 (reserved) BIOS-e820: 00000000000f0000 - 0000000000100000 (reserved) BIOS-e820: 0000000000100000 - 000000000ffc0000 (usable) BIOS-e820: 000000000ffc0000 - 000000000ffe0000 (reserved) BIOS-e820: 000000000ffe0000 - 000000000ffe8000 (ACPI data) BIOS-e820: 000000000ffe8000 - 0000000010000000 (ACPI NVS) BIOS-e820: 00000000ffff0000 - 0000000100000000 (reserved) 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. ------------------------------------------------------- This SF.Net email is sponsored by BEA Weblogic Workshop FREE Java Enterprise J2EE developer tools!
