I believe the tests were failing for Guenter due to another patch set...[1] My tests with just this series are working. >From my understanding the other failures were unrelated.[2] I've checked the patch above on top of the mmots which already has Ira's patches and it booted fine. I've used sparc32_defconfig to build the kernel and qemu-system-sparc with default machine and CPU. Mike, am I wrong? Do you think the kmap() patches are still causing issues?
