But I'm not sure whether they make sense, and I think I don't have access to the SPARC LKML, so I'll post here, and if anyone thinks the results are valid, please forward to the SPARC LKML or suggest additional tests. Background: For a while, the default Debian Linux kernel / initrd combination has generated the "Fast Data Access MMU Miss" error while loading the initd, and the issue is somewhat complicated by the fact that many 6.3.x kernels crash on the Ultra 30 (apparently a different problem that has been fixed). And it's possible, in most cases, to work around the MMU Miss error, when it happens, by reducing the size of the initrd. For example, I have a 6.4.8 kernel from www.kernel.org that works fine with a custom config file that strips out all the things that I don't need on my Ultra-30 (e.g. I only have a cheap GFX Raptor graphics card, so I can remove all the other graphics card options). I ran memtester on my Ultra-30 (this system has 1.5 GiB; I chose 1400 MiB, one loop for memtester) with no errors, and internal diagnostics all pass, so this is not likely to be a hardware problem on my system (and all my results are consistent -- kernel/initrd combinations that fail consistently fail, and combinations that work consistently work). Bisect Process: I couldn't use Debian's sparc64 config file, since it doesn't generate the kernel and initrd that Debian distributes. But I created a close approximation of Debian's config file that strips out the debug options (config-test, attached). Please see the attached notes.txt file that documents the git bisect. I started by locating a kernel that works and a kernel that fails: stock kernels with Debian-based config: 6.2 -- fail 6.0 -- fail 5.19 -- pass So the git bisect went from v5.19 to v6.0: $ git checkout v6.0 $ git bisect start $ git bisect bad $ git bisect good v5.19 Unfortunately, the "first bad commit" doesn't seem to be related to the problem, but perhaps kernel developers will see a connection. This is the end of my effort on this issue, unless anyone has additional suggestions. thanks -Stan Johnson
