What is your HT topology?
Is there any cross link between (CPU0 and CPU2) or (CPU1 and CPU2)....
You may try to disable i2c stuff in the amd8111 dir.
The code works well with S4882 and S4880.

Hi,
I am still having problems scanning the noncoherent chains connected to CPU1-3 of the motherboard I am working to support. I could temporarily work around this issue by setting the Config Base and Limit registers of those links to 0. Otherwise collapsing the chain when setting up that CPU fails. I set the Config Base and Limit registers like this: PCI_ADDR(0, 0x18, 1, 0xE0), 0x0000FC88, 0x04000103, PCI_ADDR(0, 0x18, 1, 0xE4), 0x0000FC88, 0xff050213, since there's bus 0-4 on cpu0 when i don't scan cpu1
Looking at incoherent_ht.c there are two functions that are very similar:
static int ht_setup_chain(device_t udev, unsigned upos) static int ht_setup_chains(const struct ht_chain *ht_c, int ht_c_num)
the first one warns: #warning "FIXME handle multiple chains!"
Should we not drop ht_setup_chain in favour of ht_setup_chains?
Also later on it dies apparently in amdk8_scan_chains in northbridge/amd/amdk8/northbridge.c.
Something is severely wrong with my link setup, but I double checked where the coherent and non coherent links hang off of..
Pointers?
Stefan.
