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.

are you using kmem_cache_alloc() routine inside your module ?? looks like you are allocating some memory in the interrupt context using GFP_WAIT flag enabled.

@nirvruti I suggest you go checkout http://kernelnewbies.org/. You could try visiting their forum, their IRC channel, or joining the mailing list. And if you're brave enough and informative enough you could try asking question from the main linux kernel mailing list, though I don't really recommend it. But just to inform you. You could also just join the list without posting if you're curious.
