Description Haichao Zhai 2012-06-21 00:01:20 EDT

Version-Release number of selected component (if applicable):
# uname -r

build tree

How reproducible:

Steps to Reproduce:
1.install rhel7.0 with desktop mode
2.reboot host with runlevel 5(default) 
Actual results:

By can't login what do you mean ? Black screen ? Other ? Log says everything is fine.
Comment 7 Jérôme Glisse 2014-03-07 10:25:26 EST
We believe this is already fixed but moving to 7.1
Comment 9 Jérôme Glisse 2014-07-17 11:31:31 EDT
This should already work in 7.0 but reassigning to kernel as if it is an issue than it is a kernel issue.
Comment 12 Tomas Pelka 2015-07-28 08:49:04 EDT
Hiachao would you be able to check with 7.2 kernel, are you still able to reporoduce?

Comment 15 Oded Gabbay 2016-05-09 11:45:19 EDT
I installed RHEL 7.2.0 on an x86-64 machine with AMD CAICOS GPU installed. The installation was successful and RHEL booted successfully after that. I didn't see any freezes.

This bug is stale, and it looks like it's been fixed so I'm going to close it. If you're still experiencing issues with this on the latest versions of RHEL, please feel free to reopen.
