Hi guys 

who come up to the error once or  you have some ideas about it. 

if you would like,pls.  give me some advices or a little hints ? thanks a lot.

background:
[
cpu:intel I5 (HD gpu)
os:ubuntu
work:implemented multi-encoders based on libva  for video conference. 
]


use case:
[
1.create a meeting 

2. then join it using A and B softphone; 

3.I bump the error  when rejoin the meeting using the A softphone after hang up it.
]


the below is info prompted by gdb:

[

Program received signal SIGBUS, Bus error.
[Switching to Thread 0x7fffd27fc700 (LWP 3291)]
0x00007fffe84e5236 in ?? () from /usr/local/lib/dri/i965_drv_video.so
(gdb) bt

]

I suspected the memory used by gpu  be initialized or released incorrectly.

but  what is the details about it? it is a question.

Could you provide the full backtrace for the SIGBUS bus error ?

(gdb) bt full

You should build i965_drv_video.so and libva.so without stripping the debug  information
Comment 2 haihao 2014-04-14 08:29:32 UTC 
Is the issue still exist ?

No info almost 2 years from the bug reporter, so close it.
