hi David I think there is a misunderstanding about the problem. I have two machine: - the first is a Soekris net4501 and on this machine the kernel does not boot; I can see the syslinux output about loading of /syslinux/linux and /initrd.lrp, but nothing more. The system hangs. On this system BuC3.1 runs correctly. - the second is a Soekris net4801 that I boot using the same compact flash generated for the first net4501 to verify that the compact flash has not some kind of problem; BuC4.0 runs correctly without problems, but I have seen the "libata.dma=0 not found" error.
I hope the test environment is more clear now. I think that there is a kind of incompatibility between the i486 kernel and the AMD ELAN SC520 processor that is installed on net4501. Is there a simple way to rebuild a kernel for the AMD ELAN CPU? Is a difficult operation? Can I try to built it? thanks a lot graziano Il 28/04/2011 18.44, davidMbrooke ha scritto: > Hi Graziano, > > OK.
