Hm, The reason for the: noapic acpi=off is that I don't know how to make the acpi part for my board.

I was going to say it sure looks like an interrupt problem until I saw the line which kind of makes it certain...
any reason for noapic acpi=off?

And noapic?
Your mptable says it's virtual wire mode, but that won't work with noapic.

hehe, I always thought that this is the same, my fault.
Ok, so I have probably also a bug in the mptables because without the "noapic" it hangs in the same place, yes ?.

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

No, I have still problems :(
How did you setup the northbridge?
I basically used the K8T890 and the vt8737r as the southbridges (I'm avoiding the code for vt8735 because it dose not always work)
Also, if you need to have APIC working you need:
- set the APIC to FSB mode
- set the VT8735 to APIC mode (might be already check) 0:11.0
- set correctly the bypass de-assert message - some reg 0:11.0

Ok, thanks a lot for the hints I will try this at this weekend, see what happens
