kernel boot up messages extracted from syslog (/var/log/messages)
The error message displayed on the subject line floods the kernel log buffer:
nouveau E[ PFIFO][0000:01:00.0] read fault at 0x000020f000 [PTE] from
BAR1/HOST_CPU on channel 0x00ffbdf000 [unknown]
...
[ 33.807019] systemd-journald[550]: /dev/kmsg buffer overrun, some messages
lost.
All of the useful messages I could extract out of syslog (/var/log/messages)
based on the kernel boot up time stamp is attached to this report.
I've also provided lspci -vvv & my .config as well.
I was however pleasantly surprised that the X.org & KDE did come up & appear to
be functioning fine, even including glxgears running smoothly as well.
Thank you for progressing Nouveau so far, so quickly & so nicely. And am happy
to test any patch you may want me to.

Actually, seeing how the flooding hasn't stopped, I've rebooted it to Intel
4600 video chip, disabling GTX 860m in the BIOS/firmware. However, I'm happy to
re-enable it and test any patch, if you want me to.
Thanks
