I recently updated my packages with "$ sudo pacman -Syu". After rebooting, I was getting the error:
[FAILED] Failed to start Load Kernel ModulesLooking at some other topics on this forum (such as this and this), I did an arch-chroot into my system from a USB install drive, and then did "# pacman -Syu linux" which worked, but "# pacman -Syu linux-firmware" resulted in
Failed to open file "/sys/devices/system/cpu/microcode/reload": Read-only file system
error: command failed to execute correctlyNow my system hangs when trying to boot, but I don't see the "Failed to start Load Kernel Modules" anymore. And I've been unable to fix my problem from the advice in other related topics I've looked at.

The linux-firmware package will trigger a late CPU micrcode reload which the current kernels do not support so you see the second error message.
When it hangs can you switch to a dfferent console with ctrl+alt+f2? If not can you shut the system down by pressing the power button?

Yes I am able to switch to a different console with Ctrl+Alt+F2. Thanks, I forgot about that. I was able to successfully do "$ sudo pacman -Syu linux-firmware" through that console. But my system still hangs in the main console when I boot.

Is the system configured to start a graphical environment on boot that could be hanging and causing the blank screen?
After you change tty have you examined the journal to see what failed / hung? Also `systemctl --failed`.

Ok, I figured out what was wrong. It was my fault. I usually have autologin enabled, and I tried to disable it to debug this problem by commenting out one of the lines of /etc/systemd/system/getty@tty1.service.d/override.conf but I should have removed that file altogether. My computer seems to be back to normal now. Thanks for the help!
