Description of problem: Every so often, I'd would notice my new SC1435s hang during boot up. I contacted Dell and they told me to switch the order of my terminal line from 'serial console' to 'console serial', and the caused the problem to go away. Here's what the output looked like before the hang: ======= GRUB Loading stage2... Press space to continue. Press space to continue. Press space to continue. Press space to continue. ======= [HANG] Version-Release number of selected component (if applicable): How reproducible: once or so every 3-5 reboots
Created attachment 302015 [details] Patch to fix the order or "serial" and "console"
Just curious here... why does the order of the 'serial' and 'console' commands matter?
Something about the order makes our systems hang some of the time. Reversing the order makes rebooting more reliable.
This change means grub will default to the keyboard+monitor for console instead of serial if no key is pressed. This is almost certainly not the correct solution, as this code is only invoked if you're using a serial console for installation. More investigation needs to be done into what exactly is hanging and why, and that needs to be fixed instead of this change.
