Yogesh -- please try and get the size of the attached archive from the client...

Comment 3 Yogesh 2011-05-02 08:03:22 UTC

Size of attached file to the case is 997bytes. Attaching that file with this case. This is different for bug 696166. In bug 696166, c/cpp crash files were not attached at all. In this kernel case, attachment file is small and does not have call trace.

Comment 5 Denys Vlasenko 2011-06-09 11:10:19 UTC

Yogesh, the file you attached indeed contains the following in "backtrace" element:

Call Trace:


That is, no backtrace per se.

In order to diagnose this, I need to take a look at /var/log/messages. I guess this file is included in sosreport. So please, if you will succeed in retrieving sosreport for this or similar case, please attach it to this bug.
