Hi all,
for some reason, one of my MicroOS servers is hanging in GRUB after a reboot each day. This has started some days ago, I think on Sunday.
I have a monitor connected to the servers, when I power on the monitor I see the GRUB menu just waiting for the confirmation. Hitting enter makes the machine boot properly.
probably something generates a key event, either on a keyboard or there is a noise on serial port if you have one. If it hangs reliably the noise should be quite frequent, and you should see it with evtest or reading the serial port(s). Grub can probably be configured to not boot automatically as well. Make sure the grub.cfg as well as the environment is really identical between the machines. HTH Michal
