Not that it adresses your problem, but in my case, this patch is the best one in the last months. On my good old primary LUKS/dmcrypt encrypted partitions, on an AMD Quadcore, it boosts performance from 45 MB/s w/o the patch up to 87 MB/s with it. That's just an incredibly huge performance boost. _______________________________________________ dm-crypt mailing list dm-crypt@xxxxxxxx http://www.saout.de/mailman/listinfo/dm-crypt
