[Kernel-packages] [Bug 1409393] Re: radeon GPU lockup CP stall

[JVD]

RE: previous comment - my cables are connected and screwed in tightly.
I often switch the monitors off when leaving at night. 99% of the time
the machine is left running and has no problems. 

Sometimes, however, like again today, the X-Server HANGs !!

[Kernel-packages] [Bug 1409393] Re: radeon GPU lockup CP stall

[JVD]

That last comment was from last week - I still had it in my firefox
"Restore Session" and had not pressed "Post Comment" yet.

But it just happened again today  - it looks like the frequency of this bug is 
increasing with newer kernel, xorg-server, and 
xorg-drivers-radeon releases .

Here is the info from today's lockup :

This time I did not see the 'GPU lockup CP stall' messages in the dmesg output -
it looks like the newer Xorg server & radeon_drv are capable of locking up
all on their own without a GPU lockup .

[Kernel-packages] [Bug 1428260] Re: __USE_GNU not being set by -std=gnu11 ( struct f_owner_ex not declared )

re: > please run:

No. This is a host  on my company's private LAN, and 
we are not allowed to grant access to any internal host
to any external host .
It should be obvious from the bug description what the
problem is, how to reproduce it, and what all the 
relevant packages on my system are ( the host
is fully up-to-date wrt 14.04.2 LTS as of 2015-03-04.
If there is any further information you require, 
please let me know by posting a comment to

Title:
  __USE_GNU not being set by -std=gnu11 ( struct f_owner_ex not declared
  )

Status in linux package in Ubuntu:
  Confirmed

Bug description:
  Not sure if this is a bug in libc6-dev (owner of /usr/include/fcntl.h)
  or in linux-libc-dev (owner of /usr/include/linux/header that declares struct 
f_owner_ex) but
  it definitely appears to be a bug.
  I am trying to compile code that uses the new fcntl interfaces :
 F_SETOWN_EX (struct f_owner_ex *) (since Linux 2.6.32)
 F_GETOWN_EX (struct f_owner_ex *) (since Linux 2.6.32)
  but I cannot get the 'struct f_owner_ex' structure to be declared
  using the standard system headers - I must declare it manually in my code.
  This is on a Ubuntu 14.04.2 LTS x86_64 system, fully up-to-date as
  of 2015-03-04 , with:
gcc :4:4.8.2-1ubuntu6
libc6-dev:2.19-0ubuntu6.6 
linux-libc-dev:  3.13.0-46.76

  Attempts to compile for instance this program always fail :
  $ cat /tmp/t_fcntl.c 
  #include 
  #include 
  void f(void) { struct f_owner_ex foe={0}; }
  $ gcc -c /tmp/t_fcntl.c 
  /tmp/t_fcntl.c: In function ‘f’:
  /tmp/t_fcntl.c:3:23: error: variable ‘foe’ has initializer but incomplete type
   void f(void) { struct f_owner_ex foe={0}; }
 ^
  /tmp/t_fcntl.c:3:23: warning: excess elements in struct initializer [enabled 
by default]
  /tmp/t_fcntl.c:3:23: warning: (near initialization for ‘foe’) [enabled by 
default]
  /tmp/t_fcntl.c:3:34: error: storage size of ‘foe’ isn’t known
   void f(void) { struct f_owner_ex foe={0}; }

  I can see this structure is declared in two places:
  1: /usr/include/bits/fcntl.h @ line 239:
  #ifdef __USE_GNU
  /* Owner types.  */
  enum __pid_type
{
  F_OWNER_TID = 0,  /* Kernel thread.  */
  F_OWNER_PID,  /* Process.  */
  F_OWNER_PGRP, /* Process group.  */
  F_OWNER_GID = F_OWNER_PGRP/* Alternative, obsolete name.  */
};

  /* Structure to use with F_GETOWN_EX and F_SETOWN_EX.  */
  struct f_owner_ex
{
  enum __pid_type type; /* Owner type of ID.  */
  __pid_t pid;  /* ID of owner.  */
};
  #endif

  2: /usr/include/asm-generic/fcntl.h
  struct f_owner_ex {
int type;
__kernel_pid_t  pid;
  };
  ( I am assuming I should not be using the kernel's pid type ).

  My understanding of __USE_GNU is that it is defined when 
  -std=gnu* is specified on the compile command line, or when
  _GNU_SOURCE=1 is set.  

  Only when _GNU_SOURCE=1 is explicitly set is __USE_GNU being defined 
  and the example compiles OK :
  $ gcc -std=gnu11 -D_GNU_SOURCE=1 -c /tmp/t_fcntl.c 
  OK, that worked!

  $ gcc -std=gnu11  -c /tmp/t_fcntl.c 
  /tmp/t_fcntl.c: In function ‘f’:

  /tmp/t_fcntl.c:3:34: error: storage size of ‘foe’ isn’t known
   void f(void) { struct f_owner_ex foe={0}; }
^
  Why isn't _GNU_SOURCE being set when I've asked gcc to enable GNU extensions 
with --std=gnu11 ? 

  From the "Standards" gcc info node :
   You may also select an extended version of the C language explicitly 
with ... '-std=gnu11' (for C11 with GNU extensions)

  It would appear that libc6-dev / linux-libc-dev has broken GCC's
  '-std=gnuXX' support.

  Also the fcntl.2 manual page makes no mention of _GNU_SOURCE needing to be 
defined 
  in order to use F_SETOWN_EX .

[Kernel-packages] [Bug 1409393] Re: radeon GPU lockup CP stall

[JVD]

I've been seeing this problem also, abeit rather infrequently ( about once 
every 1-2 months), 
with all Ubuntu 14.04.1 kernels issued via updates since July 2014 .

This is on my machine at work which is left on all the time and only
reboots when a new kernel is installed .

Machine:
8 core Intel(R) Core(TM) i7-4770 CPU @ 3.40GHz

RAM: 16G

Current kernel :  3.13.0-45-lowlatency
Video Card:
01:00.0 VGA compatible controller: Advanced Micro Devices, Inc. [AMD/ATI] Cedar 
GL [FirePro 2270]

I removed "radeon" from the module blacklist so it gets installed instead of 
the broken fglrx drivers whose
user-space support programs and libraries seem suited to little other than 
generating core-dumps.

I have a dual monitor setup with xorg.conf settings:

Section "Monitor"
Identifier  "Monitor0"
Option  "DPMS" "true"
Option  "Primary" "true"
Option  "LeftOf"   "DVI-1"
Modeline"1920x1080@60.0"148.50  1920 2008 2052 2200 
1080 1084 1089 1125 +hsync +vsync
EndSection

Section "Monitor"
Identifier  "Monitor1"
Option  "DPMS" "true"
Option  "RightOf"   "DVI-0"
ModeLine"1600x1200@60.0"162.00  1600 1664 1856 2160 
1200 1201 1204 1250 +hsync +vsync
EndSection


When the problem happens, the video card is left frozen displaying the last 
frames the X server emitted
(usually from the xscreensaver program).

I am able to SSH in to the host (networking still works, so the kernel is not 
totally locked up),  but 
attempts to kill the Xorg X-server fail,  and the console does not respond to 
++
"VT Switch" keystrokes.  The only thing I can do in this situation is SSH in to 
the machine and poweroff .

Before powering off, I did :
 $ dmesg -c > video_lockup.log
And I see these messages in the dmesg log :
[56089.032100] radeon :01:00.0: GPU lockup CP stall for more than 1msec
[56089.032112] radeon :01:00.0: GPU lockup (waiting for 0x0004 
last fence id 0x0002 on ring 5)

I was unable to kill the Xorg server with 'kill -TERM' .
