Kernel 2.6.22.14 questions

[Gumper]

Could anyone tell me if there are differences between the 2.6.22.14-generic kernel that's loaded with Gutsy and the 2.6.22.14 found on the www.kernel.org website? I guess I don't understand the "generic" that Ubuntu attaches to the kernel version.

I'd need to make a change to the kernel to fix a USB problem and I'm wondering if it's ok to get the 2.6.22.14 source right from kernel.org.

Ubuntu and generic kernels: Optimized kernel builds: the straight dope

== Background ==

You've all seen our kernel lineup before. In the beginning, on i386 we had
linux-386, linux-686, linux-k7, linux-686-smp, linux-k7-smp. Later, we
added specialized server kernels, and folded SMP support into linux-686 and
linux-k7.

Since Linux has always offered CPU-specific optimizations, it's been taken
for granted that this offered enough of a performance benefit to make all of
this maintenance effort worthwhile. A lot has happened to the kernel since
the early days, though, and for some time, it has been capable of loading
these optimizations at runtime. Even when you use the -386 kernel, you get
the benefit of many CPU-specific optimizations automatically. This is great
news for integrators, like Ubuntu, because we want to provide everyone with
the best experience out of the box, and as you know, there isn't room for so
many redundant kernels on the CD (only one). Many users spend time and
bandwidth quotas downloading these optimized kernel in hopes of squeezing
the most performance out of their hardware.

This begged the question: do we still need these old-fashioned builds?
Experiments have shown that users who are told that their system will run
faster will say that they "feel" faster whether there is a measurable
difference or not. For fun, try it with an unsuspecting test subject: tell
them that you'll "optimize" their system to make it a little bit faster, and
make some do-nothing changes to it, then see if they notice a difference.
The fact is, our observations of performance are highly subjective, which is
why we need to rely on hard data.

=> Generic kernel


and from the forum Topic: Is Kernel "2.6.22-14-Generic" Correct?

I'm wondering if it's ok to get the 2.6.22.14 source right from kernel.org.

Maybe these help:
- Kernel/Compile
- Ubuntu Kernel / Installing a New Kernel

Re: Kernel 2.6.22.14 questions

Thanks Rog131. I went ahead and got the kernel source right from kernel.org and compiled it. It seems to be working ok except for one thing that I noticed when I open up VirtualBox. It basically says it can't find the VB module. Apparently it didn't get compiled into the kernel.
