CentOS Stream 9 Hangs on Dell Latitude 7490 Laptop New Installation

Post by orudie » 2023/05/21 21:38:45

Hello,

I Installed CentOS Stream 9 on Dell Latitude 7490 Laptop. At first I got excited that the installation was successful. I was able to login, and run yum update, then after reboot the laptop keeps hanging. Sometimes it hangs right after I login, but sometimes it hangs while I am typing my password to login. It hangs so fast that I can't even get to /var/log/messages to see some kind of error for a hint. Any ideas?

PS: I have been running Debian 11 on this laptop for the past year without any issues, and now I really want to try CentOS Stream 9

Edit: Was able to get to /var/log/messages and saw a bunch of these errors

Don't know what the problem is, but Stream is a rolling pre-release (aka. beta)
of the next RHEL point release. It may be better to try one of the RHEL rebuilds
like Rocky, Alma, OEL, etc.

I was actually able to find a fix to the issue on other forums which others had with fedora.

For me the solution was to do the following:

# created file
vi /etc/modprobe.d/i915.conf

# added the following one line:
options i915 enable_psr=0

# ran command, which took a few seconds to finish without any output.
dracut --force

# reboot OS
init 6

# run command after reboot
journalctl -b | grep i915

I hope this helps to anyone with the same issue.
