10.5.2: Shutdown/Reboot not working


4 posts in this topic

Recommended Posts



i installed kalyway 10.5.1 on this computer:


Mainboard: Gigabyte GA-P35-DS4

CPU: Intel Core 2 Quad Q6600

HD: 2x500GB AHCI


I updateted to 10.5.2, following this guide.


But now shutdown and reboot don't work anymore.

I only see "CPU halted" or "MACH Reboot" but nothing happens.


I already tried to boot with "cpus=1".


Thanks for any help and greetings from Austria,
