Hi I was investigating a bit with a versatilepb machine, and I was trying to boot a Linux system with a root file system through NFS. It worked with Linux 3.2, but it didn't work with any later Linux version. This was the error:
[ 0.594471] smc91x: not found (-16). [ 0.595555] smc91x: probe of smc91x.0 failed with error -16 (Error -16 is EBUSY). I debugged the error, and I found that the region was being marked as "System RAM". The problem was mine, I specified (because I did not change if from previous boots) 1G as memory for the Versatile machine, which only has 256 MB of RAM Should this be a bug, or is undefined behaviour? I think it is not very difficult to check for the memory the user requests so it can be limited to 256 MB and issue a warning if it is exceeded. Thanks Marc
