[Quadro NVS 290] (rev a1) Looks like at least two entirely separate bugs here. Comments 0 and 1 look like a recurrence of bug 538163, because the patch for that got dropped from F-13. Comments 2 and 4 look like bug 561267, a nouveau bug. No idea about comment 3 which lacks any information. Please open a fresh bug and Cc me, providing full dmesg and 'lspci -nn' output. *** This bug has been marked as a duplicate of bug 538163 *** |
Created attachment 399811 [details] /var/log/messages Description of problem: Upon booting the f13 alpha livecd, I get a lot of these in my dmesg output: DMAR:[DMA Write] Request device [00:02.0] fault addr a400000 DMAR:[fault reason 05] PTE Write access is not set DRHD: handling fault status reg 2 DMAR:[DMA Write] Request device [00:02.0] fault addr a400000 DMAR:[fault reason 05] PTE Write access is not set DRHD: handling fault status reg 2 It seems to continuously spew out those messages.
