Subject: [lttng-dev] LTTng modules not loading?
Date: Tue, 22 Jan 2013 12:22:51 -0500 [thread overview]
Message-ID: <3CA1A65C03C1A34C81BBC6272782E696987933@valcartierex01.valcartier.drdc-rddc.gc.ca> (raw)
My two Ubuntu installations have the same set of LTTng modules and tools (they were all built from the same git.lttng.org packages) but different kernels and installation histories. The "clean" machine has kernel linux-virtual (3.2.0-36-virtual), the other one has linux-generic (3.2.0-35-generic). After installing LTTng and rebooting, the clean machine does *not* load the lttng kernel modules, while the other one does. /etc/modules and /etc/modprobe.d are the same, the .ko are present in /lib/modules/<kernel>/extra in both cases. The clean machine's lttng kernel modules can be loaded using modprobe without demur, so there is no problem there.
At first I thought this was because the clean machine had not installed the dkms package yet, but adding it made no difference: the lttng modules do not load.
How can I get the clean machine to load the lttng kernel modules at boot time?
