It does boot with 1st option, virtualization, enabled.

Enabling the 2nd, VT-D, causes freeze while boot (see screenshot).

*********** MASS BUG UPDATE **************

We apologize for the inconvenience.  There are a large number of bugs to go through and several of them have gone stale.  Due to this, we are doing a mass bug update across all of the Fedora 21 kernel bugs.

Fedora 21 has now been rebased to 3.18.3-201.fc21.  Please test this kernel update (or newer) and let us know if you issue has been resolved or if it is still present with the newer kernel.

If you experience different issues, please open a new bug report for those.

Comment 5 Volker Braun 2015-01-30 00:41:57 UTC
Its a known bug (probably in Lenovo's BIOS) that VT-D conflicts with the "discrete graphics" BIOS setting on the W530. You can boot with VT-D enabled if the integrated graphics is selected, and you can boot with discrete graphics if VT-D is disabled. If that is not what you meant then please clarify on the graphics BIOS setting.

Thanks Volker, I'll give it a shot!

Feel free to close this bug if the cause isn't in the kernel.

Closing based on latest discussion.
