Hi,

I have here a Dual-Athlon Box, with a AMD760MPX Chipset and AMD768 IDE.

In the base 2.4.18 kernel there seems to be no support for the IDE-Chipset

So I tried 2.4.19-rc3-ac1 and I got more APIC errors, than I can count :))

So my question.

Does anybody know where to find a patch for the IDE-Support to the plain 2.4.18 kernel,

or which version of the 2.4.19-rc<x>-ac<x> is stable enough at the moment to run such a box.

TIA for any help...

It is supposed to be 'standard'. If you enable:

CONFIG_IDE=y
CONFIG_BLK_DEV_MODES=y
CONFIG_BLK_DEV_HD=y
... it should work. The amd74xx was seperate, it was a "Viper" chip-set. I believe that the newer AMD Chip-Sets are generic.

They are not generic, although they are fairly similar. You need the -ac tree right now for the 760MP/MPX IDE, although the port wont be hard

Pending for 2.4.20

For -ac we are chasing some bugs in the Summit support. 2.4.19-rc1-3 should you fine. The summit fix stuff is waiting until either I or more likely the IBM guys looking at it figure out what broke. Its important enough I've left it in broken for some boards until found.

I've got two of these machines running with 2.4.19-rc2 at the moment; no APIC errors you speak of. Before, they were running 2.4.19-pre9-ac2, also with no APIC errors. Perhaps you have a hardware problem?

I have Tyan Tiger MPX (AMD768) working just fine with my patch set. However, it currently has only single CPU. Patch is for 2.4.19-pre7.
