I simply add "mem=32m" to the kernel command line, and the kernel runs longer, at least a bit. However, it than stops with nearly the same issue: Unable to handle kernel paging request at virtual address, but different addresses. Tried "16m, 64m" and other values, all behave in different way. Resulting to a crash at the position w/o any parameter or a bit later on. Since I am not so familiar MIPS and especially the fact that our hard- and software is more than closed, I am asking you guys to point me where to spend more time on in order to get this issue fixed and fire up a kernel on this box. I am sure there some more guys around using the smp8634. Is it necessary to load the microcode in order to get the kernel starting up? Maybe we don't need the audio/video-ucode but irq-handler-ucode looks very usefull ;-) Do we just have to copy this code at a certain memory address? Thank you in advance ... Regards, Andi
