Hello,

Please take a look at this lttv error with the mainline kernel
2.6.32.9 on ppc64.

lttng: patch-2.6.32.9-lttng-0.198
lttv-0.12.30-02102010
ltt-control-0.79-01022010

LTTV crashed with this error:

This post, http://lists.casi.polymtl.ca/pipermail/ltt-dev/2010-February/002189.html,
describes the same error on 32 bit system. By not having the
LTT_ALIGNMENT set, shouldn't it just work in my case?

Thanks in advance for your help!
