This message is a reminder that Fedora 18 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 18. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At that time this bug will be closed as WONTFIX if it remains open with a Fedora 'version' of '18'. Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, simply change the 'version' to a later Fedora version prior to Fedora 18's end of life. Thank you for reporting this issue and we are sorry that we may not be able to fix it before Fedora 18 is end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged change the 'version' to a later Fedora version prior to Fedora 18's end of life. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete.
*** Bug 1047169 has been marked as a duplicate of this bug. ***
At least a potentially related nv0_vm_map_sg NULL crash is being discussed here: https://bugs.freedesktop.org/show_bug.cgi?id=64774
Description of problem: Upgraded to Fedora20 today. No idea what causes these. My X window are freezing periodically. Maybe its related? Version-Release number of selected component: kernel Additional info: reporter: libreport-2.1.10 cmdline: BOOT_IMAGE=/vmlinuz-3.12.5-302.fc20.x86_64 root=/dev/mapper/fedora_hampton--pc-root ro rd.md=0 rd.dm=0 rd.lvm.lv=fedora_hampton-pc/swap rd.luks=0 vconsole.keymap=us rd.lvm.lv=fedora_hampton-pc/root rhgb quiet kernel: 3.12.5-302.fc20.x86_64 runlevel: N 5 type: Kerneloops Truncated backtrace: #1 nv50_vm_map_sg in nouveau #2 nouveau_vm_map_sg in nouveau #3 nouveau_vma_getmap.isra.14 in nouveau #4 nouveau_bo_move_m2mf.isra.15 in nouveau #5 ? nouveau_vm_map_at in nouveau #6 nouveau_bo_move in nouveau #7 ? nouveau_vm_map in nouveau #8 ttm_bo_handle_move_mem in ttm #9 ? ttm_bo_mem_space in ttm #10 ttm_bo_move_buffer in ttm
the latest patch mentioned on lkml thread only changes hard system locks into soft locks for kernel-3.12.6-300.fc20.x86_64. the suspend/resume cycles works pretty stable for rawhide kernel-3.13.0-0.rc7.git0.2.fc21.x86_64. afaics, the 3.13 kernel contains some acpi/pm fixes in the nouveau area.
