hi, my system (dmesg below mail) occasionally goes into ddb at boot.
it shows the following message;
kernel: protection fault trap, code = 0
Stopped at 0xffffffff80437d70: pushq %rbp
(null)() at 0xffffffff80437d70
end trace frame: 0x0, count: 10
ddb>
how do i stop this from happening?
once it goes into ddb, i usually type "boot reboot" and the system reboots
just fine.
dmesg;
