Without "nosmp", the kernel crashes when starting up the application processors. It appears that the crash is caused by something calling a NULL function pointer. Kernel profiling is currently disabled (I haven't sorted out yet what should be done with respect to the new profiling infrastructure). Another caveat is that Itanium 1 machines need to have reasonably recent firmware with correct ACPI information. For Big Sur (e.g., i2000 machines), firmware 117C seems to be good enough (this firmware is available from hp's workstation support web site, for example). I'm not exactly sure what the earliest firmware version is that will work properly. But if you're encoutering interrupt routine problems, the culprit is probably bad firmware. I apologize for releasing such an incomplete patch, but I'm in the middle of a family emergency which is keeping me from working full-time. I expect things to be back to normal sometime later next week. In the meantime, I appreciate (as always) all help to improve the ia64 kernel. Thanks, --david
