Ummm.. I disagree. Avtually it's pretty simple. Boot the system with root file system mounted over NFS. The compile a Linux kernel natively on the board. This is doing all you want: stressing network (lots of DMA), stressing the memory (lots of context switches and heavy RAM use), etc. If your system survives this, you can be 98% sure that it will pass any other test as well. > E.g., I had a subtle memory timing issue that only turned up under > very peculiar circumstances under linux; this was very difficult to Of course there are really weird cases, but fortunaltey these are rare exceptions.
