Subject: Regression in 4.11 - PowerPC crashes on boot, bisected to commit
 5657933dbb6e

My Powerbook G4 Aluminum generates a fatal splat early in the boot process, just 
after identifying the driver for the disk. Unfortunately, it turns off almost 
immediately, thus I cannot report the message. After this bug has been 
triggered, the system clock has been reset to Dec. 31, 1969. I assume this is a 
side effect of an uncontrolled DMA operation.

This problem has been bisected to commit 5657933dbb6e ("treewide: Move dma_ops 
from struct dev_archdata into struct device").
