 |
|
I have a problem running user mode linux kernels under 2.6.7-gentoo. I compile the 2.4.26 kernel with the UML patches and run it. It doesnt find skas3 stuff or /proc/mm, then goes on to segfault at the following line:
if(switcheroo(data, prot, addr, segment_start, size) < 0){
if i take this same binary and run it under 2.6.7 vanilla it is fine. (again, not finding /proc/mm or skas3). I read that they may crash immediately if the kernel uses the 2g/2g memory addressing instead if 1g/3g, so i compiled my UML kernel with 2g/2g enabled. Still crashes. Any ideas why? |

There are lots of things that could go wrong. How are you trying to run the UML kernel once compiled?
It isn't finding SKAS because you probably haven't patched your host kernel.
If you are using HIGHMEM in the 2.6 UML, turn it off. |
