            Bug ID: 105221
           Summary: kernel modeswitch fails on Fedora 27 on Evergreen
                    (Radeon HD5850)
           Product: DRI
           Version: unspecified
          Hardware: x86-64 (AMD64)
                OS: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: DRM/Radeon
          Assignee: dri-devel@lists.freedesktop.org
          Reporter: brouhaha@fedoraproject.org

With Fedora 26 I had sporadic problems with the system crashing at the first
kernel mode switch, before entering the LUKS passphrase at boot time, but I
could hit reset and usually the second time it would work. With Fedora 27 this
happens to me consistently every time. The only way I can successfully boot is
to use "nomodeset" on the kernel command line, which then causes issues for my
X session.

My system has Asus Sabertooth 990FX R2.0 motherboard, AMD FX-8350 CPU, and
Radeon HD 5850 graphics card. I'm running Fedora 27 with kernel
4.15.3-300.fc27.x86_64.

Fedora Bugzilla shows someone else having that problem with HD 5450. Maybe its
a general Evergreen problem.

--- Comment #1 from Eric Smith <brouhaha@fedoraproject.org> ---
Replaced Radeon HD 5850 (midrange Evergreen) with Radon R7-240 (low-end GCN 1st
gen), and it boots fine without needing to remove rhgb or add nomodeset.
