- Please make sure that your BIOS is up-to-date.
- Dump your DSDT into ASL and grep it
#acpidump -d > your.asl
#fgrep -i '"Windows' your.asl
If this displayed something like this:
"Windows 2001"
then try
set hw.acpi.osname="Windows 2001"
from the boot loader and see the difference. This won't fix anything
and you may be seeing other problems, YMMV.
- Does the following command sequence produce the same error messages?
#iasl -c your.asl
If so, you may want to fix your ASL, compile it into AML, put it somewhere
in the root filesystem, and tell boot loader to use it.
# vi your.asl
# iasl your.asl
# mv acpi_dsdt.aml /boot/
# echo 'acpi_dsdt_load="YES"' >> /boot/loader.conf
For more hints and detailed instructions please refer to the
Config and Tuning handbook page posted on submit@ for reviewing.
Thanks.
