My suggestions on how to do this would be to create an array of uint64_t and save TSC values (rdtsc()) into it at specific points in the atkbd/syscons console init. You can then print out the deltas between array entries once the console is fully initialized. Moving the rdtsc() calls around should allow one to determine where in the atkbd/syscons init the long pause is happening. -- John BaldwinReceived on Wed Apr 21 2010 - 13:29:46 UTC
