I have reported a similar panic on the Fedora users' list. My BIOS is HP 786F2 version 1.04. Instructions and a download are given here: https://h30434.www3.hp.com/t5/Desktop-Hardware-and-Upgrade-Questions/Trying-to-update-the-bios-on-dc-5800-mt/m-p/5745831 ... but my previous attempts to save BIOS settings have been unsuccessful. I do not know if an update would fix the problem and the 4.13 series still works. I will await developments...
After following the BIOS-update instructions from the URL given in Comment 1 above I am now running 4.14.8-200.fc26.x86_64 on that box. HP Compaq dc5800 Microtower/2820h The new BIOS is 786F2 v01.60 10/26/2015 Before that I had tried reversion to factory settings, which had no obvious effect, and writing the extracted files to a DOS-format CD, which apparently could not be read at the appropriate time.
Updating to BIOS v01.60 solved my problems with booting any kernel newer than 4.13.X as well.
The same happened to me with a DC5800. runs 4.13.16.202 ok but failed on start up on 4.15.12 error "acpi_ex_system_memory_space_handler" . Upgrading BIOS on device to 1.6 from the HP website ( The BIOS upgrade appears in the Windows OS selection ) has fixed the problem . now OK .
