KNOWN ISSUES

Bug of latest syslinux package

In some new Linux distributions, the "syslinux" package in their official software repositories is the version 4.04. It will cause segment fault for a fatal bug, and mic will failed with syslinux installation errors.

The solution is to install the patched "syslinux" package in MeeGo or Tizen's tools repos, until the official released one being fixed.
