Hm, interesting. When booting with 3.11 from Saucy, scrolling seems quicker (my interactivity local is buggered by a keyboard monitor switch which some day I should replace), at least I could not really read what scrolled by while I could with 3.13. And looking at /proc/mtrr I found a write-combining range added which was not done with 3.11:
reg03: base=0x0fc000000 ( 4032MB), size= 8MB, count=1: write- combining Cannot say why right now but that could well explain the slowdown. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1434581 Title: Console extremely slow with 3.13 and newer kernels for certified servers with Matrox G200er2 or similar To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1434581/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
