Hi all, when opening a LTT kernel trace, lttv-gui reports some "Cannot find pin_in in schedchange" messages and segv's soon afterwards.
My configuration on target: x86, multicore (via hyperthreading), kernel 2.6.36,
patched with LTTng 0.245, modules 0.19.6, LTT control 0.89.
I am using the VMware image of the LTTng demo machine (latest downloaded), this
is 0.12.37. Attached is the shell output.
BTW: While configuring the patched kernel, we couldn't find the Kernel Option
"Immediate value optimization" in menuconfig. However, this has been mentioned
in the manual:
http://git.lttng.org/?p=lttv.git;a=blob_plain;f=LTTngManual.html#installlttng
Might this be a serious problem leading to crashing lttv-gui?
Thanks in advance, regards,
Klaus Birken
