Re: Facing problem while patching LTTng 0.9.5 with linux kernel 2.6.21

Hi Mathieu,

Good news.. Now I am able to generate some trace data.
The problem was mounting debugfs.
So when I gave "mount /mnt/debugfs" command after booting, then it
started generating the trace information.

But unfortunately the viewer gave the following bundle of errors. 

************************************************************

test-devsys:/home/rrao/NFS/NFS_test/home/sreddy# lttv-gui

So is the data generated is proper or something is missing in the data.
If you want is will send those generated files.
Please let me know about this.
