Looks like something is freeing a bunch of io-mappings at a time. Notice, how creating fifo 2 for the second time does not ioremap anything, so there is caching in action. Maybe this is a non-issue. -- Configure bugmail: http://bugs.freedesktop.org/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are the assignee for the bug. _______________________________________________ Nouveau mailing list [email protected] http://lists.freedesktop.org/mailman/listinfo/nouveau
