--- Comment #5 from Konstantin Belousov <k...@freebsd.org> --- In the first message, the backtrace shows copyout_nosmap_std(). Anyway, do you observe a difference in the reported features before and after ucode load? Also, for the trap, disassemble the copyout function and show which instruction faulted. -- You are receiving this mail because: You are the assignee for the bug.
