 |
|
For the Ryzen 5 1600 I needed the following in my /etc/grub/default to keep it stable:
| Code: | | idle=nomwait rcu_nocbs=0-11 amd_iommu=on video=efifb:off kvm.ignore_msrs=1 pci=msi |
I upgraded to a Ryzen 7 3700X a couple of months ago, and it booted right away. I've had zero problems.
The question is: can I remove those kernel options and have stability with the 3700X?
Thanks.

| I'm not using any of those options on a 3950X (except amd_iommu=on, but I need that for KVM), works fine. |
