Commit 6532eb17baff6e61b427f29e076883f8941ae664 r600g: add htile support v16 cause a gpu lockup on juniper with Dishonored in wine. https://www.dropbox.com/s/7w140vtr48xb8vt/Dishonored.trace.bz2 this trace reproduce the error.

bug #59592 is similar but I should be using the fix from that bug already.

mesa, libdrm, xf86-video-ati and linus kernel are all git from yesterday. 3.0 Mesa 9.2-devel (git-ce3dfa1)

Comment 1 Jerome Glisse 2013-02-14 15:41:55 UTC

Does it happen without --enable-gallium-llvm also does it happen when running with R600_HTILE=0 env variable ?

Comment 2 Thomas Lindroth 2013-02-15 11:06:59 UTC

It happens with --disable-gallium-llvm and/or R600_HTILE=0. It doesn't happen with R600_HYPERZ=0.

Comment 3 Alex Deucher 2013-02-20 21:23:58 UTC

Does the patch on bug 60969 help?

workaround

Most likely does not help (not for me at least). However this patch should work around the issue.

Comment 5 Thomas Lindroth 2013-02-21 20:07:41 UTC

The workaround patch posted here prevents the lockup in dishonored. The one in bug 60969 doesn't fix dishonored but it prevents an other lockup in google-earth. I assumed it was the same issue. Lockups in darwinia and multiwinia has also been fixed but I don't know which of the patches did that.

Please check if below patch fix the issue:
