I haven't seen a freeze for a while, I'm guessing that a recent kernel update
has resolved the freeze.

Instead, I occasionally get a chrome tab going screwy with a segfault in
nouveau:
Mar 12 13:40:23 ibm007470 kernel: nouveau 0000:01:00.0: Xorg[2838]: Unknown
handle 0x01c69fda
Mar 12 13:40:23 ibm007470 kernel: nouveau 0000:01:00.0: Xorg[2838]:

Mar 12 13:40:23 ibm007470 kernel: nouveau 0000:01:00.0: Xorg[2838]: validate:
-2
Mar 12 13:40:23 ibm007470 kernel: show_signal_msg: 6 callbacks suppressed
Mar 12 13:40:23 ibm007470 kernel: chrome[6053]: segfault at fffff5c81b30075a ip
00007f10c41be05c sp 00007ffd499625b0 error 5 in
libdrm_nouveau.so.2.0.0[7f10c41bb000+7000]

Going to raise that with the chromium team to see if they can get more debug
info that could address a potential underlying cause.

Current kernel: Linux ibm007470 4.15.6-300.fc27.x86_64 #1 SMP Mon Feb 26
18:43:03 UTC 2018 x86_64 x86_64 x86_64 GNU/Linux
