Solved Can't load compiled acpi

Clockwork

Clockwork

I compiled acpi and am trying to boot with it in order to fix some weird kernel spam in the console.

acpi_tz0: _CRT value is absurd, ignored (256.1C)

I constantly get this type of message and overwrite the output in the tty.

My laptop tolerates this: HP Compaq nx6320

I read this http://wp.xin.at/archives/5312 and this https://docs.freebsd.org/doc/9.2-RELEASE/usr/share/doc/freebsd/en/books/handbook/ACPI-debug.html

My loader.conf has the lines:
Code: 
acpi_dsdt_load="YES"
acpi_dsdt_name="/boot/acpi-modded.aml"

nothing has changed after a reboot.

# kldload acpi_dsdt
Code: 
kldload: can't load acpi_dsdt: No such file or directory
 
If nothing changed, then your changes didn't work. You can't load it using kldload as it's not a kernel module.

Provide a diff between original and modified asl code.

As you can see there are changes. But I don't understand why they didn't work.

The iasl command seems to have thrown an error. I don't see any errors in stderr.log though.

Code: 
root@hp:~ # iasl ./acpi-modded.asl 2>./stderr.log
Error 6092 - Could not open file "2" (Source Input) - No such file or directory

root@hp:~ # cat stderr.log

Try without redirection which doesn't seem to be working for you (which shell?). Is the file you put to /boot/ actually non-empty?
 
I understand, it seems he swore at > 2. I switched to the sh shell and tried again.

Code: 
# iasl ./acpi-modded.asl 2>./stderr.log

Hooray, it worked.
Now sysctl shows the correct value!

Code: 
sysctl hw.acpi.thermal.tz0._CRT
hw.acpi.thermal.tz0._CRT: 101.1C
