May be right. At the time, I did not have libreoffice-gnome or
libreoffice-gtk installed, and the whole interface was weird, probably
plain mesa. After I installed the gtk interface, I have not been able to
reproduce the problem. Thanks. -Mark

Created attachment 125931 [details] GPU crash dump GPU hangs when using LibreOffice Writer. Always happens every once in a while, while typing. It goes out to lunch for 15 seconds and then comes back when the chip resets. System does not respond at all during that time. I lose the keystrokes in the meantime. It seems to be only on this one document... maybe a weird font rendering issue? Tried adding intel_iommu=igfx_off to boot params but that did not help, so I removed that option for this test. `uname -m` x86_64 `uname -r` 4.6.0-1-rt-amd64 Linux: Debian Stretch Machine: Lenovo X1 Carbon 4th gen Display: Built-in 14" WQHD 2560x1440 IPS, 300 nits Batch buffer: Attached dmesg debug: Attached (using "drm.debug=0x1e log_buf_len=1M") Syslog excerpt: =========================================== Aug 20 13:51:10 walnut kernel: [ 353.815999] [drm] stuck on render ring Aug 20 13:51:10 walnut kernel: [ 353.816385] [drm] GPU HANG: ecode 9:0:0x86dffffd, in Xorg [2650], reason: Ring hung, action: reset Aug 20 13:51:10 walnut kernel: [ 353.816389] [drm] GPU hangs can indicate a bug anywhere in the entire gfx stack, including userspace.
