I checked log, there is apparmor denail for /dev/nvidiactl
Feb 20 16:28:07 Silver kernel: [ 117.797833] audit: type=1400 audit(1487604487.352:57): apparmor="DENIED" operation="open" profile="webbrowser-app" name="/dev/nvidiactl" pid=3124 comm="webbrowser-app" requested_mask="wr" denied_mask="wr" fsuid=1000 ouid=0
since I could not reproduce issue in my pc, I tried in reverse way, denying apparmor acess to /dev/nvidiactl and I could see exact same crash.
So To validate that I need your help.
Add path in profile:
$ sudo vim /etc/apparmor.d/user.bin.webbrowser-app
add /dev/nvidiactl --> [/dev/nvidiactl rw,]
Reload the profile
$sudo apparmor_parser -r /etc/apparmor.d/usr.bin.webbrowser-app
$webbrowser-app // should works.
I am still wondering why crash is not happening in any other machine(including mine)
