1. Please describe the problem:

Dell T7500 won't boot any fedora 29 kernel starting with 4.19.13-300.fc29.x86_64
Appears to hang right after "Probing EDD"

2. What is the Version-Release number of the kernel: 4.19.13-300.fc29.x86_64

4.19.13-300.fc29.x86_64
4.19.15-300.fc29.x86_64
4.20.3-200.fc29.x86_64

3. Did it work previously in Fedora? If so, what kernel version did the issue
   *first* appear?  Old kernels are available for download at
   https://koji.fedoraproject.org/koji/packageinfo?packageID=8 :

Worked previously, stopped working at 4.19.13-300.fc29.x86_64 https://koji.fedoraproject.org/koji/buildinfo?buildID=1176140

Verified that 4.19.11-300.fc29.x86_64, 4.19.12-301.fc29.x86_64 work fine.



4. Can you reproduce this issue? If so, please provide the steps to reproduce
   the issue below:

Attempt to boot with any fedora 29 kernel 4.19.13-300.fc29.x86_64 or later exhibits problem.


5. Does this problem occur with the latest Rawhide kernel? To install the
   Rawhide kernel, run ``sudo dnf install fedora-repos-rawhide`` followed by
   ``sudo dnf update --enablerepo=rawhide kernel``:

Unknown

6. Are you running any modules that not shipped with directly Fedora's kernel?:

yes, but panic happens so early those modules aren't loaded.


7. Please attach the kernel logs. You can get the complete kernel log
   for a boot with ``journalctl --no-hostname -k > dmesg.txt``. If the
   issue occurred on a previous boot, use the journalctl ``-b`` flag.
