A different question. Is the system utilizing IOATDMA at all at the
point of suspend/resume? Any RAID5/6 volumes? Or NET_DMA is on?
Dave,
I just booted with ioatdma blacklisted in /etc/modprobe.d/blacklist.conf
With ioatdma no longer loaded, I no longer see the problem with resuming
from suspend.
Does ioatdma have suspend/resume support?
No ioatdma has no suspend/resume or any pm ops support. It'll be on my
todo list. I suspect the DMA engine went into an unknown state with the
suspend/resume.
