The trace.dat is working, I have been able to open the same trace.dat file with the previous version of kernelshark. Next, I tried to open an old trace.dat (created with old kernelshark) with the latest version and that also failed. I can send you the trace.dat and also a .deb package for Debian which you can install and test, but it will take a few days. I can only do it after the t64 transition is over. -- Regards Sudip
