Hi Rafael, since you didn't like the idea of calling the driver callbacks with just one cpu enabled, we gave your patch: "MM / PM: Force GFP_NOIO during suspend/hibernation and resume" a try and i can confirm that this fixes the issue on s390. Will this go in 2.6.33/stable? greetings, Sebastian _______________________________________________ linux-pm mailing list linux-pm@xxxxxxxxxxxxxxxxxxxxxxxxxx https://lists.linux-foundation.org/mailman/listinfo/linux-pm
