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

Sobczak Wojciech

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

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

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

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.

Cheers,

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

Acatually, the blacklist is only needed on the SuSE kernel because they are
using a backport of the 2.5 ACPI code. However a tiny bit of code used to
ID and enable the summit bits sliped through and the quick solution was to
blacklist it until the proper fix is included.

Right now there are no x440 specific patches pending for Vanilla 2.4 or
Vanilla 2.5. As issues are found and resolved, patches will be submitted
first thing for inclusion into mainline.

thanks

x440 doesnt work with the ACPI in the 2.4 update from Intel either. I don't
really care whether IBM fix that before it goes into 2.4.22pre1 or after.

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?

regards
WS

It has no failover (or multipath) support.
