Assumptions:

• The platform:
  
  Code:

  anisha@linux-dopx:~/> uname -a
  Linux linux-dopx 2.6.34-12-desktop #1 SMP PREEMPT 2010-06-29 02:39:08 +0200 x86_64 x86_64 x86_64 GNU/Linux

• The kernel downloaded is the latest stable one from kernel.org.
• We let the defaults remain (make no changes) in the options of make menuconfig.
• Simply type make, make install, grub-update, and reboot.

Now, following these assumptions, are we still required to make some additional changes to files or compile some extra drivers to ensure a error free reboot?

If yes, then on what things do those changes depend on?

...hoping you did save the (unchanged) options, of course. I have compiled a kernel or two in my life, and I always assumed there to be no config info in the downloaded package (that would be totally useless, anyway). I always run menuconfig and save the config, even if no changes were made...so, in brief:

...will not do...I guess...

But, that's just my feather of thought...

But, in answer of the question: no, I never make any extra changes other than running menuconfig to get an educationally guessed config to compile with...

And, again...my two cents...

yeah, when we press the exit, it saves the changes? You are frightening me now~! ;-)

What? You guess is that it will fail or not?

also, this site is old now, but still does it hold totally true? http://www.cyberciti.biz/tips/compil...kernel-26.html

If you wish to continue with your old (and working) configuration, use your old .config file:
cp /boot/config-old-version-number ./.config (after unpacking it)
and run: make oldconfig (or whatever you prefer/need, just make sure it's using your already existing .config).

Writing mkinitrd -o initrd.img-2.6.25 2.6.25 is same as mkinitrd -o initrdXyz ? I didn't understand the trail of numbers at the end.

Hehe, no, it does'nt automatically save anything, you'll have to tell it to save the config...and, sorry to have scared you...

If there's no config at hand, it will, unless you use jens' approach and use what the system already has.
