    Last week, some readers reported that they were experiencing a Linux kernel panic. The kernel pushing the panic button is one of the many problems in Linux. Basically, this is probably a situation where the kernel fails to boot properly and therefore the build fails to run. During the snickers process, the core is not directly populated.
