Subject: Regression in 4.11 - PowerPC crashes on boot, bisected to commit 5657933dbb6e
Date: Wed, 1 Mar 2017 21:26:34 -0600	[thread overview]
Message-ID: <5bc9c08f-58aa-ef26-8891-4837e2d4184b@lwfinger.net> (raw)


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").
