I observed the behavior on bd2d0210cf in a qemu-kvm install of openSUSE 11.3 (x86_64) on *totally* different host - an AMD quad-core. I did /not/ observe the behavior on 16828088f9 (yet). I'll run the test a few more times on 1682.. Additionally, I am building a bisected kernel now ( cb20d5188366f04d96d2e07b1240cc92170ade40 ), but won't be able to get back at it for a while. I hope this helps. -- Jon -- dm-devel mailing list dm-devel@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/dm-devel
