I believe you will have to build a generic kernel.org kernel
configured without that support, something I have underway right now,
using 2.6.20-rc4. I was amazed at the number of options I found
turned on that a proper 'make oldconfig' should absolutely never have
turned on. My scripts take care of everything but grub.conf for a
kernel install, so when its done all I should have to do is reboot
since I'm already running 2.6.20-rc4. Several things I found may
even account for the apparent slowness of later kernels. Things
like 15 seconds to launch firefox on an xp-2800 athlon with a gig of
ram?


Gene,

Could you share some of these "Several things I found"? I'm having
the same problem with slow firefox launching on a very similar
system. I'm currently running vanilla kernel 2.6.19.2.

Thanks,

John

Basicly I did a make xconfig in the kernel tree I had already built
and was running, with an eye to getting rid of that which isn't of any
perceived usefullness to me. If, as you go thru the xconfig screens
item by item, you read the help that pops into the lower right corner
of the window, and it says "if you don't know what this option does,
you probably don't need it, say N". By the time I got down to the
bottom of 'block devices' I'll bet I'd turned off a hundred things
that were being built, and which had no earthly use to me, but the
previous 'make oldconfig' had enabled them. With this newer compiler
seemingly being as slow as it it, that cut the build time by about 7
minutes, down to 24 IIRC, but I can recall building a kernel for this
machine in under 8 minutes back in the mists of time. And the system,
once booted to it, does seem a bit snappier at some operations. I
think I can probably cut that much more the next time I have half an
hour to work in an xconfig window.

Firefox launch times? Not a huge speedup there so far. Sorry.

Are you going to try to disable SElinux in the kernel and see what
happens?? Ric

Already did, Ric. Logwatch has a bunch of complaints from pam but things
are working. It indicated some sort of disappointment over a cron
started amanda backup session, but the session itself ran as usual.
