It may be due to a hard drive or hard drive failure since the panic references "AHCI".


In addition to the EtreCheck report suggested by @BDAqua you should also run DriveDx and post the report here using the "Additional Text" icon which looks like a piece of paper.

Not much I can tell from that report, others might though.

What temperatures does this App report? Especially the GPU.

This App can be used to speed up the fans, all my iMacs would be dead without it.

Never ever ever drop fan speeds below the speed that the Mac itself is calling for.

Workable but harder for me to work with...the Note tool on the bottom of this editor's toolbar, as shown in the image, to copy and paste the output from EtreCheck. In a Reply before you click post, look for this to add longer texts...
