Priority: medium
Bug ID: 74982
Assignee: xorg-driver-***@lists.x.org
Summary: System crash with HD7770
QA Contact: xorg-***@lists.x.org
Severity: critical

Version: unspecified
Component: Driver/Radeon
Product: xorg

Hi,

I have a Radeon HD7770 with an abit pro motherboard, running Fedora 20.

xorg-x11-server reports version 1.14.4-6.fc20.

I have a repeatable complete system crash (screen goes blank, numlock
un-responsive etc), in some conditions when a drop down is selected in certain
programs.

Under XFCE4, if I load gimp and select export, a drop down list appears. If I
click on this, everything freezes, screen goes blank, and system crashes.

I get the same now with inkscape, and some graphical export functions under
freecad.

Given that both these programs have graphics functions , I kind of got the
feeling that it may be related to the graphics driver. I can't think of any way
of proving this however.

Oddly the same happens in audacity when click the drop-down bar to change
audio, not obviously this is not a graphical application. But again the crash
is occurring on a drop down box.

This used to happen in eclipse under KDE... actually when I expanded a tree
view in the debug window. But then I switched to XFCE4 so not sure if that
issue is still present.

Sorry if this does not belong here. Please let me know if there is anything
else I can do or try to help with the debug.


Thanks,



Martin.

Please attach your xorg log and dmesg output.

Actually I have just tried this in gnome-classic, and I have not managed to
crash the system as yet.

Sounds like something related to XFCE and the graphics driver perhaps?

I think I've seen the same issue sometimes on pitcairn. Now I've looked into it
a bit and found the way that reliably reproduces it for me with eclipse Kepler
SR1 and XFCE on Fedora 20 (compositor is disabled):

1. Select "Window" - "Preferences" in the eclipse menu.
2. In the "Preferences" dialog, select the Formatter tab in the tree
("C++"-"Code style"-"Formatter")
3. Click on the "Active profile" combobox to open the list of formatter
profiles. I have few custom profiles added there and when the last of them is
selected as current, the listbox is goes beyond the borders of the
"Preferences" dialog (as shown on the attached screenshot). If the
"Preferences" window itself is close enough to the top of the screen so that
the part of the listbox would end up outside of the screen area, then it always
results in gpu lockup, otherwise it works as expected.

Thanks Vadim, I'll try and reproduce your steps in Eclipse.

(In reply to comment #3)

If the "Preferences" window itself is close enough to the top of the screen so
that the part of the listbox would end up outside of the screen area, then it
always results in gpu lockup, otherwise it works as expected.

Sounds like it ends up trying to render outside of the screen boundaries... for
which compositing (even just xcompmgr -a) should be a good workaround.

Is there anything about GPU VM protection faults and/or the lockup itself in
dmesg when it happens? If so, can you attach that here?

Hi,

I was able to re-produce Vadim's Eclipse fault. As soon as there is enough menu
items to go beyond the top of the screen the system locks up.

I cannot see anything in dmesg that relates to a GPU fault.

dmesg

I've managed to switch to VT afer lockup (it doesn't always work), and there is
some output regarding the lockup in the attached dmesg.

Hello, this is my first time commenting a bug report, so, sorry for my english
and sorry if I don't do it right...

I managed to figure it out, trying a simple test, on XFCE;
if you are using the Adwaita Theme, changing it to default
XFCE theme the problem with the drop-down list is gone, so,
I don't know if the problem is the radeon driver, maybe is
related to GTK+3 and Adwaita.

Steps to reproduce.

(with Adwaita Theme)
1. Launch xfce4-terminal
2. Edit --> Preference
3. Go to Advanced Tab
4. Click on Codification drop-down list
5. Your X server freezes, or monitor turns off (my case)
with out been able to do nothing no even switch VTs...

(now with XFCE Default theme)
1. Launch xfce4-terminal
2. Edit --> Preference
3. Go to Advanced Tab
4. Click on Codification drop-down list
5. Voila!!, nothing happens you can change your codification
and use any drop-down list with out hesitate or have afraid
of lose the work...
