I've just updated to current Current, so I may send fresh dump do you need it? But I hope I've described it more detailed ;-) Again, if I set break point at install_ap_tramp this function start to work correctly. (No trap at write access). And panic occures from other place (And I unable to fix it by debugging ;-)) in mp_machdep.c. I don't have remote power control over that machine so I have only two hours to test smth with direct access. After that I will go to home. I can access to that machine remotely but it may stuck whith some big enough probability at any reboot. It seems that this machine has many ACPI related problem, but this is only machine I could use for testing ISA drivers for SMP, so I don't have choice ;-( Now I'll try to understan what part of that ACPI commit I could leave and which to backout to minimize search area. rik
