Free some memory on resume before re-loading modules #568
Conversation
Intel wifi driver wants to allocate large contiguous memory blocks (for example with Intel BE200 it's 128k). Try to force some memory (possibly pushing some apps into swap) and then force memory compaction - just before loading wifi drivers back (depending on device, module either gets loaded, or just bound to the device). Do this by using dd to allocate 512MB of memory. The amount is large enough to force swapping, but it's still significantly below the swap size (1GB) so it doesn't trigger OOM. Fixes QubesOS/qubes-issues#9869
