IBM x440 problems on 2.4.20 to 2.4.20-rc1-ac3

Helo,
I'm trying to boot from linux kernel 2.4 tree
i've installed rh 7.1 dist, but system seems only 3 procesors, so i made 2.4.20 kernel with smp without NUMA support and i saw 4 processors. Next 2.4.20 with numa support, and system hangs on mounting root filesystem (no scsi devices found, ide devices lost interruption, no keyboard found etc etc)
Next 2.4.21-rc1-ac3 without NUMA, 3-processors available
with NUMA support and summit/exa support and clustered apic support kernel boots, found scsi devices but hangs on it with lost interruption, also with ide devices and so on
machine has 4 HT processors and 8GB of RAM
any ideas or help?

i don't wat to use 2.5.x kernel.....

regards

SuSE works well, at least the SLES edition does.

I'm not sure that any of the other 2.4 kernels work properly, though I can't say I've tried the latest updates to other distros - they might work, but I doubt 7.1 does - that's very old.

but shoudn't it be platform independent? this is only kernel or meaby i need new gcc... or meaby something else?....

You need the kernel itself. It's the apic handling that's mostly different.

ok, thanks to all folks for help,
i'm now using 2.5.68 with linux-isp patch for qlogic support, system is working nice, i see all 8 processors but cpuinfo shows only 199 bogomips, but system performance is much much higher :), so meaby this is some kind of not important bug.
as for now i will try to swich to 2.4.21-rc1 as Keith Mannthey gave me working kernel config for 2.4

so now i've got one of them (servers) for kernel testing :)

from the battle field - i tryied to run on 2.5.68-mm3 tree but system hangs on processors recognition.

as for qlogic support with linux-isp - is this driver with failover support?

It has no failover (or multipath) support.

I has nothing to do with gcc, Alan mentioned the magic (or cursed is probably the better choice :) word, ACPI. The kernel in SLES 8 has the x440 blacklisted so ACPI gets turned off automagically :)

As John mentioned, you can use a generic kernel provided its recent enough AND you configure it properly for the box.

Perhaps someone could submit the x440 blacklist entry to the base kernel ?

That sounds like a bug. Make sure you ACPI off for x440 if you are testing and see if that helps

For vendor kernels you need Red Hat AS 2.1 or UnitedLinux 1.0. At least I don't believe other vendors rolled kernels for x440 but I may be wrong about that - certainly I can believe Debian or Gentoo might have.

x440 is sufficiently weird it needs its own extras and that makes it hard to support for vendors.

Support for the x440 landed ~2.4.21-pre4.
Try a more recent 2.4 kernel.

thanks
