<div dir="ltr">Well, if you really only want to find bugs in kernel code (specifically linux drivers) there was a recent white paper that came out that used Dynamo Rio to instrument and analyze the kernel.

</span>There is only one approach to understanding any code. Reading the code<br>
and understanding how different things interact. If you have doubts<br>
you can always ask here.<br>
<br>
Read Linux Device Drivers? Though that will still not prepare you<br>
for actual code. Eudyptula Challenge?<br>

Just running the kernel might not always point out bugs.<br>
