The nvc0_fifo_isr() routine is essentially called from a signal handler so it's not possible for me to trace back in the kernel what triggers it to get called. I've reviewed recent git changes in drm/nouveau; nothing jumps out to me but I'm not a nouveau guru. I don't think testing an older kernel (like whatever you were running previously) would help, but certainly couldn't hurt.
There are no bug reports filed about this issue upstream, so I forwarded this one up. If we don't get a response, then it might be worthwhile for you to approach ben skeggs directly via IRC on #nouveau. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/925048 Title: [GTX 580] X seems to hang a login prompt -- PFIFO errors in dmesg To manage notifications about this bug go to: https://bugs.launchpad.net/nouveau/+bug/925048/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
