x38 rebooting(power management) issue and Pci audio drivers
1 1

Question

hi!

this is not really a "big" problem, but whenever I have installed something that needs a reboot, the system only manages to shut down screen, mouse and keyboard, all hardware continues active so i always need to press the button twice manually. perhaps this is a bios power management setting?

 is it possible to adjust bios to automatically accept the request too reboot? i had no similar issues with ubuntu and mint earlier. 

edit: audio problem solved nicely...;)

i figure i can load into the installer and remove it from there?

i guess this should/could be the code?

 

 mount -uw /

rm -rf /System/Library/Extensions/****.kext { Replace **** with KEXT extension }

I found the source of the problem it seems...for some reason a PCI pwr management thing kills the screen. when i did a clean install without installing the Juli@ sound card drivers the system runs clean, unfortunately i can't use the audio card tho. tested a few workarounds like ALSA, EnvyHT etc. but still brings me back to the blackscreen just before the login screen. its a common error it seems for people with this audio card or with PCI audio cards in general. so ill just keep it clean until later. perhaps someone else finds this information useful as well:)
