This looks like a regression. Under F15 when I wrote large files to a pendrive, the system would become a little sluggish. Now it essentially freezes until the write terminates. What I mean is that the UI is almost completely unresponsive; even clicking between two terminal windows is so slow that you can see the window contents refresh, followed several seconds later by the frame. Fully updated F16 with KDE, Intel Core 2 Dual, 4GB RAM, Intel onboard graphics. The pendrive is an 8GB Patriot Xporter (a year or two old) under USB-2 with no intervening hub. poc -- users mailing list users@xxxxxxxxxxxxxxxxxxxxxxx To unsubscribe or change subscription options: https://admin.fedoraproject.org/mailman/listinfo/users Guidelines: http://fedoraproject.org/wiki/Mailing_list_guidelines Have a question?
