I encountered a similar error on fedora 25 - sometimes with chrome, and much
more frequently with the webkit based native/default web browser.
The video display, mouse, keyboard would all freeze, but the ssh login would
work - allowing one to see the nouveau cache errors in dmesg.
I tried a few arguments from
https://nouveau.freedesktop.org/wiki/KernelModuleParameters/ , and developed
the following workaround:
Add nouveau.nofbaccel=1 to the Linux kernel line during booting. On fedora it
can be done by making changes to /etc/default/grub so that a line similar to
this exists: GRUB_CMDLINE_LINUX="verbose nouveau.nofbaccel=1"
After this, install this command line using grub mkconfig:
grub2-mkconfig -o /boot/grub2/grub.cfg
Reboot - preferably manually inspect that the command line has the flag.
After this change, the performance is a bit worse - but hardware acceleration
is still detected by desktop manager - hence it works in full graphics mode.
Can you try this command line flag on boot on the line which specifies the
Linux kernel to load.
