We have two Fedora bug reports: https://bugzilla.redhat.com/show_bug.cgi?id=519154 https://bugzilla.redhat.com/show_bug.cgi?id=556990 with many users affected. Many upstream users suffers from that problem as well. Since this is firmware bug this should be fixed in firmware. Intel is aware of issue but we do not have F/W solution for that for long time. Changing default options in upstream kernel is problematic. Since 2.6.33 we have different memory allocations to avoid failures due to buddy allocator fragmentation. It is optimized for normal usage case, but with swcrypto when and skb's have to be linearized memory usage by driver increase about 2 times. So I would like to swcrypto options to fedora, and work for better solution upstream (or rather hope Intel will solve that).
