[ltt-dev] ** ERROR **: Kernel/LTTV event size differs for event tree_call_rcu_bh

[Naresh Bhat]

Hi Mathew/Alexandre Montplaisir,

Thanks for clarifying. I have the following versions

1. My linux kernel version is - *2.6.32.21*

2. lttv version is
    root at x86-generic:~# lttv --help
   * Linux Trace Toolkit Visualizer 0.12.29-02022010*

3.  lttctl version is
    root at x86-generic:~# lttctl --help
   * Linux Trace Toolkit Trace Control 0.78-04122009*


I have tried with the following combinations on x86 32bit generic
architecture.  The *GREEN* colour one's are best combination which I found
from compatibility list. But I have marked it as failed because I am getting
following error.

*lttv -m textDump -t tc-lttng-002 -d -v > tc-lttng-006.log

** ERROR **: Kernel/LTTV event size differs for event
tree_call_rcu_bh: kernel 4, LTTV 8
aborting...
Aborted

*lttv failed to parse trace files in textDump mode*
