This normally does not mean the swap is problematic. The kernel is
probabaly trying to access a NULL pointer(thus the address is 0xc, which
is often the offset,

It might be implemented so. I would ask the designers.

As far as I know, ICT guys are working on standardlize of the firmware
interface, this might be a good reference.

Yeeloong 8xxx (based on Loongson2F CPU) uses Silicon Motion 712 as
graphics chip, connected to CPU with PCI bus.
Yeeloong 8133 (based on Loongson3A) uses the embed GPU of AMD RS7

I had this working before with debian.

I agree with you, there's some cs5536_mfgpt.c file in
arch/mips/loongson/common/cs5536 which gets build (CONFIG_CS5536_MFGPT=y).
But exported symbols differ, structs differ, function names differ, etc.
I don't think this will work. But I'm not a coder. So may
Lemote has 3A motherboards(mini-ITX and others), but due to power/price
etc. we don't think it is suitable to build a 3A box like miniPC.
For the motherboards themselves shipment will be a little bit
troublesome so we have not put it to retail pages.
Recently we are planning to have a promoti

Thanks Fuxin. I meant the "Loongson 3A laptop" mentioned here:
