I tried this version with the same results.
It seems that I've got something weird in my compilation setup.
I set up a serial console to see the messages from boot and near the beggining I get:
"Unknown bustype PCI - ignoring"
The code that generates this is at arch/i386/mpparse.c:
> } else if (strncmp(str, BUSTYPE_PCI, sizeof(BUSTYPE_PCI)-1) == 0) { > ... > } else if (strncmp(str, BUSTYPE_MCA, sizeof(BUSTYPE_MCA)-1) == 0) { > ... > } else { > printk(KERN_WARNING "Unknown bustype %s - ignoring\n", str); > }
BUSTYPE_PCI is defined at include/asm-i386/mpspec_def.h:
#define BUSTYPE_PCI "PCI"
so that first "if" statement translates to
> } else if (strncmp(str, "PCI", 3) == 0) {
which should be always valid for "PCI ", and that message should never appear :(
Well, sorry about the noise, I must dig deeper now...
