Tsk. This typically means you're faulting very early in the boot process. Thus is typically caused by trap'ing & then calling vm_map_lookup() out of vm_fault() prior to setting up the vm maps. The vm_map_lookup() faults & you get caught in an infinate recursion ending in a ksp not valid. First thing I'd try is temporarily making the ALPHA_MMCSR_ACCESS case in trap() always fatal for a kernel-mode trap. This should catch the initial trap & give you a clue as to what's going wrong. Sorry for my delayed reply. My wife & I just moved into our new place. No phone service yet, much less DSL. Blah.
