I had a look at it. Do I need to do anything else? :) Seriously. Can you please do the following: 1) Enable CONFIG_GENERIC_IRQ_DEBUGFS 2) mount debugfs 3) Before suspend collect information from there cat /sys/kernel/debug/irq/domains/* and cat /sys/kernel/debug/irq/irqs/$N where $N is the interrupt which does not fire anymore 4) suspend/resume 5) Collect the same data as in #3 Thanks, tglx _______________________________________________ Intel-gfx mailing list Intel-gfx@xxxxxxxxxxxxxxxxxxxxx https://lists.freedesktop.org/mailman/listinfo/intel-gfx
