Surely it will go well, don't enable too much of the new stuff, try to
be conservative with SLAB/SLUB.

I have been using latest kernel for many years without problem. But this
2.6.27.x series of kernel really does not work well on my P3-700. I have
tried 2.6.27, 2.6.27.1, 2.6.27.2 as well as 2.6.27.3. All crashed after
about 1 day of operation.
Maybe some options need to be disabled to use 2.6.27 kernels on old
hardware... didn't find anything with Google, though.
Maybe 2.6.28 ....

Or maybe you just don't know how to properly build a kernel.

Aaagh! It's too early in the morning to drink!
Speaking of not building kernels correctly, I'd been doing "make
oldconfig" for ages; what a Godsend, right? About a month ago I was
watching the build go by, and I was seeing all this stuff I never would
have asked for. So I popped into the config and unchecked a mountain of
drivers and other things (e.g. mobo fix workarounds) that were just not
required for my machine.
So either oldconfig glossed over this stuff, or I missed it all when I
was doing the oldconfig. Does make oldconfig automatically Y/M certain
items without prompting? I thought it didn't.

I'm ashamed to admit that I don't know that much about initrd. I don't
use it (I don't think--no mention of it in lilo.conf--I just build the
few drivers necessary to boot into the kernel), and my kernel is well
over 1 MB compressed.
What's the size limit about?

The current kernel config is certainly a monster compared to days gone
by.
But it was about time I went through and cleaned up the kernel and
scripts, anyway. This machine has been upgraded every release since
Slackware 9.0 and there were just a few too many things being complained
about on bootup.

I don't believe that it does. I have also used "make oldconfig" forever,
and haven't noticed what you describe. I suspect you just missed a
section when you did the original "make menuconfig" and it's carried over
for a while.
Every now and then when I feel ambitious, I'll go through the whole thing
again and look for things I might want to change. Usually don't see
anything unexpected.

Back when I was using Caldera OpenLinux and older versions of Ubuntu, I
used a script to compile the kernel. Now, i am using make-kpkg. Both
methods have been working fine until this 2.6.27!
OK, tell me, Monk Dan: what option(s) in .config affected the stability
of the kernel on my slow P3-700+Asus CUBX PC?

The size of the kernel has *nothing* to do with whether you need an initrd
image or not, you clueless Win-droid. My current kernel (2.6.27.3) is
about 2.2Mb, and requires no initrd. The *only* reason you would ever
need an initrd is if the drivers you need for startup (such as filesystem)
are not included in the kernel.
Now run along and update your virus definitions, or whatever it is that
you Win-tards do with your computers.

In the old days there was a 2M limitation on the size of the kernel.

Now that USB drives are so big, is there still a limitation?
Vi$ta could load drivers from a NTFS partition during installation. What
about Linux? Still relying on a floppy diskette?

No, the limitation is gone, at least in the last half of the 2.6 series
of kernels.

During installation Linux usually reads the drivers from the CD-Rom/DVD
media.

If there is new stuff that isn't flagged in your oldconfig then the build
assumes the default answer, which is mostly "Y". |

Ummm, no. Wrong again, n00b. It's interesting that you clipped out what
you said before, rather than quoting it in your reply. I'll put it back
in here below:
| Quote: | I usually removed most SCSI and network card drivers. If you could

|
Right there is a direct quote of what you said. You *clearly* stated that
if you reduce the kernel to about 1Mb, you don't need an initrd. That
statement is absolutely wrong, and you can't twist it any other way.
Like I said, run along and play with your toy "operating system", you
drooling Win-droid. You don't know shit about Linux, and never will.
