Unable to boot DTA after Bios update with AMD AGESA Code 1.0.0.4C

[btspce]

HP Elitebook 745 G5 bios update includes an AMD Agesa microcode update that broke DTA booting (and regular Linux kernel booting) This has since been fixed in an updated Linux kernel but we cant update bios on these computers running DTA. Can we get an updated kernel for DTA as this presumably breaks booting on all amd devices with the new microcode ?

I'm not sure whether you're still seeing this issue or you've found a workaround, but a recent pull request I submitted (#306) fixed AMD/Ryzen issues that I was having as well as at least some of those reported by others.

Please take a look at my "integ" branch (latest binary releases) or in @ChubbyAnt's fork (latest binary releases), both of which use an updated Buildroot target (2019.02.6 LTS) and an updated Linux kernel (4.14.146 in the 4.14 LTS series) per the pull request above. I'm using the resulting PBA to unlock drives successfully on a Gigabyte "X470 AORUS ULTRA GAMING" with a Ryzen 2400G CPU. (I haven't been able to sort out yet whether the fixes that were added in ~4.18 kernel per RH bugzilla notes were backported to 4.14 LTS.)

ChubbyAnt's releases/tree are only tested on NVME+Windows, while mine are tested on Windows&Linux but primarily SATA. If these don't fix your issues then please follow up.

NOTE that both of these forks also use SHA512 for password hashing, which means they're not backward compatible with 1.15.1 "vanilla". You'll need to uninstall (actually revert, preferably --revertnoerase then --revertTPer) the DTA 1.15.1 SEDutil before attempting to install the updated SEDutil PBA.
