I use this XF86 driver for my Asus TNT card and it VERY quick.

I really don't think you have a linux problem - it sounds like bad hardware.
the kernel version shouldn't be the issue.
can you run ok with just one cpu installed? are both the same exact
version (did you buy both at once? were they retail or oem? if
retail, were the manuf dates the same?)
in the bios there's an SMP setting (forget the wording) that says 1.1
or 1.4. I chose 1.4. try that and see if it helps.
other than that, did you custom build a kernel or use off the shelf
ones? I am using a bone stock mandrake/redhat 6.0 - seems little need
to custom build a kernel these days, since autoprobing and using
modules allows your kernel to pull in just what it needs and nothing
more.

What is the ut_id field in the utmp structure actually use by. I know
that init sets it, but which programs actaully use it?
Does the id have to be unique? I don't think that it does even though
sysv-init enforces unique id fields in its inittab.
I need to know whether I can get away without initialising it in the
system I am working on.

I replied to your last post but I misread it - I thought you were
having irq issues (the only problem with boards like these).
what is the kernel saying when it panics? what kinds of things were
you doing? graphics/x? lots of disk i/o? what boards do you have
installed?
do a cat /proc/pci and cat /proc/interrupts to start with.
also, maybe you should suspect your ram. try setting the bios a bit
less aggressively. are you overclocking, also?

How do I populate the "struct sockaddr" used in the bind() call? I have
looked around without much success. I would like to connect the socket
to a IP port (e.g. 123.45.6.78:9090). Please help. Code source will

my system is pretyy vanilla - meaning, no soundcard ;-) I am a
business user and have no need for crap like that. its still the weak
link in the pc arch - win95/98 have hacks to deal with plug-n-pray irq
issues, etc.
anyway, I have a millennium 2 pci and mystyque agp installed in
adjacent slots. the placement of the ethernet card was important - it
seemed to work in only 1 slot (currently a 3com 3c59x). a dec TULIP
showed the same slot sensitivity as did an SMC card.
I have a tekram scsi card in another slot. not sure if this one
mattered. but the basic issue is: this board is more sensitive to
slots than say an asus.
try swapping slots (??)

You won't have much success without much effort.

You could of course just compile the parts of the kernel you want into modules,
though I doubt that'll work with ip :-)

BTW: Don't let the magic words 'kernel programming' worry you. Its like DOS

Of course questions can be asked too, as long as they are not stupid

I'm trying to use 2.2.6 as a server, and it doesn't seem to be able to
support more than a few hundred processes. I have made the obvious
changes in linux/task.h (# proc) and linux/limits.h (# of open files),
and it still appears to be running out of file descriptors.
I didn't have this problem with 2.0 kernels, they ran when patched. What
has changed?

We ran into problems on RedHat 5.2 with glibc 2.0.
ps, top and last failed to show more then the 8 first characters in

We therefore limit usernames to 8 chars.
