Subject: Blank console but X11 works on MCP79 - old regression since 3.8
Date: Fri, 17 Nov 2017 15:26:00 +0100 [thread overview]
Message-ID: <201711171526.01053.linux@rainbow-software.org> (raw)
Hello,
I've just been hit by this old bug which is still present in 4.14:
https://bugs.freedesktop.org/show_bug.cgi?id=80675
On MCP79 (ION), when stolen memory is set to 32MB in BIOS, console is blank
but X11 works. When the stolen memory is increased to 64MB, console works
fine.
Bisected it to this:
4f6029da58ba9204c98e33f4f3737fe085c87a6f is the first bad commit
commit 4f6029da58ba9204c98e33f4f3737fe085c87a6f

drm/nv50-nvc0: switch to common disp impl, removing previous version
Signed-off-by: Ben Skeggs <bskeggs@redhat.com>
It's a big change so I'm not able to do more debugging.
