How to fix bootup kernel error How to fix bootup kernel error
------------------------------- -------------------------------
The HVM may pause on boot, showing a fixed cursor. If the HVM pauses on boot and shows a series of warnings, visit [HVM Troubleshooting](/doc/hvm-troubleshooting/#hvm-pauses-on-boot-followed-by-kernel-error) for a fix.
After a while a series of warnings may be shown similar to this:
BUG: soft lockup - CPU#0 stuck for 23s! [systemd-udevd:244]
To fix this:
1. Kill the HVM.
1. Start the HVM
1. Press "e" at the grub screen to edit the boot parameters
1. Find the /vmlinuz line, and edit it to replace "rhgb" with "modprobe.blacklist=bochs_drm"
1. Press "Ctrl-x" to start the HVM
If this solves the problem then you will want to make the change permanent:
1. Edit the file `/etc/default/grub`.
1. Find the line which starts:
~~~
GRUB_CMDLINE_LINUX=
~~~
1. Remove this text from that line:
~~~
rhgb
~~~
1. Add this text to that line:
~~~
modprobe.blacklist=bochs_drm
~~~
1. Run this command:
~~~
grub2-mkconfig --output=/boot/grub2/grub.cfg
~~~
The HVM should now start normally.
