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"). Larry
