We run memtest86+ from within our Linux-based hardware test suite. This has always worked quite well. It was painful to get running at first (kexec was still young then and wasn't included with our distribution's kernel), but is very= easy to use now. Unfortunately, though, we've hit a new snag with our latest platform versio= n. This is based on Ubuntu 8.04. Specific software version info: kernel version 2.6.24-19-generic kexec-tools-testing 20070330 released 30th March 2007 memtest86+ version 2.01 The problem is that memtest86+ reports numerous memory errors when booted v= ia kexec, booting directly into memtest86+ does not turn up these errors. I suspect a device is getting mapped into memory and not deallocated prior = to kexec execution (but I may be putting my ignorance on display). Any ideas?
