| |
Hi,
I am trying to build a linux kernel for a small form-factor PC. I have so far failed to create a working kernel.
Output of /cat/proc/cpuinfo as given by the hardware vendor:
> processor : 0 > vendor_id : SiS SiS SiS > cpu family : 5 > model : 0 > model name : ff/00 > stepping : 5 > cpu MHz : 200.008 > fdiv_bug : no > hlt_bug : no > f00f_bug : no > coma_bug : no > fpu : yes > fpu_exception : yes > cpuid level : 1 > wp : yes > flags : fpu tsc cx8 mmx > bogomips : 398.95
I gather that is a SiS 55x System-on-a-chip.
I am using T2[1] as build-system. It (currently) tries to build the kernel from 2.6.25.7 sources. When booting the kernel it built the system stops after:
Decompressing Linux... done. Booting the kernel.
At the bottom of the screen it says:
BUG: Int6: CR2 00000000
And nothing else.
My kernel-configfile can be downloaded from [2]
I am confident that the build-system in itself is sound. I can boot the system it created on a variety of different systems including QEmu, but not on the target with the CPU given above. But I have very very little experience in building system like this from scratch.
I am quite new at this sort of thing, so please be gentle if I forgot the most vital part of information required to help me. I will gladly provide anything asked for.
If someone is really extremely keen on helping I can also send out one of the machines I am trying to get this up and running on and a copy of the development host-VM I am using.
Ciao, MM
