--- Comment #27 from Leho Kraav (:macmaN :lkraav) <leho at kraav.com> ---
Hi. I'm hitting the same problem now with 5.4.0-rc4+ series, Latitude 7400 CFL.

Mucking around in Firefox, suddenly graphics hang. Fortunately I can switch to
console, so I can gracefully terminate some apps, but no way to get back into
GUI unless reboot.

I just had 38 days perfectly stable uptime on 5.3.0, before upgrading to
5.4.0-rc series for improvements in S0ix suspend residency.

Unfortunately some kind of a serious graphics regression has happened here.
