Carr --- Moving the set of vbar_el2 was not the cause of improvement. I just saw two runs of over 2,000 successful kldloads before a hang without it. I also saw the system hang on the first load last night. I wonder if success of the first load makes the next load more likely to succeed, e.g. because the module reloads at the same address. Clock frequency does not seem to matter. I ran my kldload/kldunload loop w= ith powerd on running at 1416 MHz and with powerd off running at 600 MHz. --=20 You are receiving this mail because: You are the assignee for the bug.=
