[ltt-dev] Fwd: Re: Lttng and Tiny Core?

[medvedm@ZIN-TECH.COM (Medved, Michael)]

Per Mathieu's email, I'm moving my question to this mailing list.

In response to his question - I've already built the tiny core 2.6.33.3 kernel and installed it and it seems to work just fine.  So when I drop the patch into this build is when things start going awry.  

The 2.6.33 (already patched for TC) can be had here:

Usually these questions go through the mailing list,
ltt-dev at lists.casi.polymtl.ca.

You should probably try booting your kernel without the lttng patches applied to
make sure it's not just a matter of a missing driver (e.g. proprietary nvidia
?) from your kernel per se.

The problem may not even be related to lttng, so it would be good to check that
first. So you should try a 2.6.33.3 kernel without lttng applied.

Thanks,

Mathieu
