Similar problem has been detected: I think it happened for the first time when I tried to login into a webmail account with two passwords (one to enter and another to decipher mailbox). I got a message saying "Oops...Gnome...crashed...xwayland...contact developer". It would also crash when I use other applications; I would get the same message and it would bring me back to the login screen. reporter: libreport-2.8.0 backtrace_rating: 4 cmdline: /usr/bin/Xwayland :0 -rootless -noreset -listen 4 -listen 5 -displayfd 6 crash_function: pushbuf_krel executable: /usr/bin/Xwayland global_pid: 1381 kernel: 4.8.8-300.fc25.x86_64 package: xorg-x11-server-Xwayland-1.19.0-1.fc25 pkg_fingerprint: 4089 D8F2 FDB1 9C98 pkg_vendor: Fedora Project reason: Xwayland killed by SIGABRT runlevel: N 5 type: CCpp uid: 1001
Even though this is Xwayland crashing, none of the code in the backtrace points toward Xwayland itself, but rather mesa and the nouveau driver. https://bugs.freedesktop.org/show_bug.cgi?id=94727
Edit: this is actually an abort() in nouveau drm code, not a crash. In drm/nouveau/pushbuf.c 222 static uint32_t 223 pushbuf_krel(struct nouveau_pushbuf *push, struct nouveau_bo *bo, 224 uint32_t data, uint32_t flags, uint32_t vor, uint32_t tor) 225 { 226 struct nouveau_pushbuf_priv *nvpb = nouveau_pushbuf(push); 227 struct nouveau_pushbuf_krec *krec = nvpb->krec; 228 struct drm_nouveau_gem_pushbuf_reloc *krel; 229 struct drm_nouveau_gem_pushbuf_bo *pkref; 230 struct drm_nouveau_gem_pushbuf_bo *bkref; 231 uint32_t reloc = data; 232 233 pkref = cli_kref_get(push->client, nvpb->bo); 234 bkref = cli_kref_get(push->client, bo); 235 krel = &krec->reloc[krec->nr_reloc++]; 236 237 assert(pkref); 238 assert(bkref); <=== *** here *** 239 krel->reloc_bo_index = pkref - krec->buffer; 240 krel->reloc_bo_offset = (push->cur - nvpb->ptr) * 4; 241 krel->bo_index = bkref - krec->buffer; 242 krel->flags = 0; 243 krel->data = data; 244 krel->vor = vor; 245 krel->tor = tor; 246 [...]
Moving to libdrm for a better opinion.

Hi, Ilia has posted in upstream bug [1] a patch that might help [2], I've prepared a scratch build of mesa with this patch for Fedora 25: https://koji.fedoraproject.org/koji/taskinfo?taskID=17242295 Can you try updating mesa with these packages and try to reproduce? * Note: This is a scratch build, meaning it will be automatically removed after a short time.

Hi, have you had time to try the test package from comment 20 ?
The patch is included in mesa 13.0.4, does it still occur with an up-to-date mesa package?
This message is a reminder that Fedora 25 is nearing its end of life. Approximately 4 (four) weeks from now Fedora will stop maintaining and issuing updates for Fedora 25. 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 EOL if it remains open with a Fedora 'version' of '25'. 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. Thank you for reporting this issue and we are sorry that we were not able to fix it before Fedora 25 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 this bug is closed as described in the policy above. 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.
Fedora 25 changed to end-of-life (EOL) status on 2017-12-12. Fedora 25 is no longer maintained, which means that it will not receive any further security or bug fix updates. As a result we are closing this bug. If you can reproduce this bug against a currently maintained version of Fedora please feel free to reopen this bug against that version. If you are unable to reopen this bug, please file a new report against the current release. If you experience problems, please add a comment to this bug. Thank you for reporting this bug and we are sorry it could not be fixed.
