Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I know I am late on the scene, but the issue was not really solved and this may be of interest for other people passing by.
Indeed I have recently investigated the exact same issue:
-> it seems Dovecot does something unsupported by Via U2250 when installed with any flavor of Linux-64bit, ending up with recurrent system freezing and no log.
-> I experienced that situation on 2 Debian 7/64bit mail servers powered with U2250 (running Exim + Dovecot-imap).
There are 3 options:
-> find an alternate to Dovecot and keep the rest of your software and hardware configuration (alternates: uw imap, courier, cyrus - I achieved stability with courier but it was not convenient to me)
-> keep going with the same software solution but change hardware (Kikinovak's costly option)
-> change the running instruction set of your processor by installing an x86-32bit Linux (my choice - same packages selection, same config files and it works perfect)
Hope it will help.
Resource 1: two weeks of tests going back and forth between 3 64bit servers, 2 of them powered by U2250.
Resource 2: a bunch of people struggling with a U2250 config and Dovecot - in French: linuxfr.org/forums/general-general/posts/crashs-etranges-de-serveur
Resource 3: your thread.
