Hi,
You have the hang with coreboot already running?
How did you setup the northbridge?
Maybe just fixing PCI-ids to K8T890 may work (no K8M890).
Most of the regs looks similar! Just looking at their values
Also, if you need to have APIC working you need:
1) set the APIC to FSB mode 2) set the VT8735 to APIC mode (might be already check) 0:11.0 3) set correctly the bypass de-assert message - some reg 0:11.0 4) set correctly (force A2 from APIC FSB to low) some reg 0:11.0
You need to setup correctly also 0:0.7 offsets 0x70-0x7f
Otherwise it will not work.
Basically call vt8237r_cfg and disable vt8237r_vlink_init
I will go on holiday tomorrow afternoon,
Rudolf
