Hello, I've been using my own kernel (kernel.org 2.6.28.4 based with the at91 patch and modified board file) with an emdebian-grip-lenny filesystem. Overall I've been very happy with the system, but I've been getting a kernel "oops" lately.
My question is could there be any problems from not using a debian kernel? The oops says, "Internal error: Oops - undefined instruction: 0" that makes me think the the program (I think sshd is the offending program) is making a kernel call that isn't supported by my kernel? Anyway the oops is attached if anyone is interested. thanks, Paul
