I was hoping someone with more HP expertise may know a solution, or at least have some ideas. The issue is as follows:
I bought a HP EliteBook 735 G5 with Ryzen and Vega graphics. It (CPU/GPU) is supposedly supported by the linux kernel.
The notebook came with Win10 preinstalled, which isn't that bad. However, I work mostly with Linux servers and web applications/development/clusters operating under Linux. Having a Linux machine at the ready is a big help. And so I thought I would boot up a liveCD of some distro and see how the drivers are handled and if it is at all possible to use AMD with Linux nowadays.
The thing is: no distro has booted up. Either the screen goes blank (pure black, no reponse for CTRL-ALT-DELETE) or it shows a kernel panic.
This happens while booting either a liveCD or a setup application. The furthest I can get is the boot menu (either GRUB or UEFI systemd boot I think it's called). After making any choice the kernel crashes and either I only see a black screen or sometimes (can't really predict which power cycle) I see kernel panic.
I have tried:
- Disabling secure boot
- UEFI boot
- CSM boot
- Disabling Fast Boot
- Disabling all onboard devices
And launching distros:
I have found some indications that IOMMU might be the culprit on Ryzen-Linux builds, however I don't seem to be able to change anything about it in Setup Menu.
Has anyone tried and succeeded? I have the latest firmware update (7/29?).
