[SOLVED] Kernel Panic within a minute from boot #124

Closed horus1963 closed 3 years ago

Hi,

When I install these extensions on my Threadripper 3960x system, I get a kernel panic within a minute from login. Below are the last two kernel panic logs:

If you need any more information I will do my best to provide them.

Thanks

Hi, thanks for the issue. Is this happening every time and preventing you from using the kext? I do not have a Threadripper but as for as I know it is the same architecture as Ryzen cpus and others using Threadripper have reported to have no problem running.

horus1963 commented 3 years ago

Yes, it is happening every time. May be it is something specific to my setup. What would you need to help narrow it down?

horus1963 commented 3 years ago

It looks like that having an undervolt in the BIOS of the motherboard is what was causing the problem. With the undervolt the system will kernel panic when SMCAMDProcessor.kext is loaded. Without the undervolt, both the kext and the system are working great so far (has been running for more than 24 hrs with no problems).

Thanks a million for this.
