Created attachment 22203 [details] [review] Properly handle the case abw_count == 1 There is NetBSD-specific code in os-support/bsd/alpha_video.c. This code doesn't work on ev6 systems. This is because the code assumes there is 2 mappings, one dense and one sparse. On ev6 there's only one mapping, and the code access abw[] out of bound. Fix: check abw_count and if it's 1, use the same mapping for dense_base and memory_base.
