I'm refreshing an old supermacro server. the server used to have cent os installed. I just installed ubuntu 16.04 on it. but after installation, it refused to boot. I could boot into recover mode, but for normal boot, it will be stuck at this screen.

in the above call stack, it has cpu_startup_entry. I wonder if this is related to failed cpu initialization? the system has dual cpus.

Hi, welcome to the fora.

Which Ubuntu did you install? Server or desktop?

Hi,

Thank you.

I tried Ubuntu 14 desktop first, and saw some cpu problem at the installer. I googled, found someone mentioned a kernel bug which might cause similar behavior.

the bug gets fixed with a newer kernel. So I tried ubuntu 16 server. the installation was successful, but when booting, I saw this.

I tried recover mode console， it could work.

Booting in recovery mode, please run
sudo lshw -sanitize > lshw.txt and post lshw.txt in CODE tags. It will show the hardware details.
