... mmmhhh, I have not a commercial debugger and I have never used kgdb, also, I've tried to compile the kernel with the kgdb support but it does not finish the compilation. At the moment my unique debugging technique is printk, do you think is necessary to setup kgdb ? With printk, in this case, I don't understand what I can print because there are not a lot of values to print. I suppose the problem is in the initialization of MMU or IRQ and this problem is a side effect. For example, in prep_setup.c there is a write to 8000081c to enable the L2 cache, but in the MVME5100 programmers manual I haven't find the address of the corresponding register so I'm not sure of the effect of this write. >You might want to see the MCPN765 and PrPMC750 ports that are in >in the 2_5 tree.
