For node amaura, Sean has the memory replaced. But I can still see this BAD gran_size stuff in dmesg: https://pastebin.ubuntu.com/p/vH6bP9xkHd/
Also, I found another Intel Purley 2S node "secchi" is behaving like this as well. Works with T/X but not B/C/D. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1821573 Title: Unable to boot 4.15 / 4.18 /5.0 kernel on an Intel Denlow SDP Status in ubuntu-kernel-tests: New Status in linux package in Ubuntu: Incomplete Status in linux-meta-hwe package in Ubuntu: New Status in linux source package in Bionic: Incomplete Status in linux-meta-hwe source package in Bionic: New Status in linux source package in Cosmic: Incomplete Status in linux-meta-hwe source package in Cosmic: New Status in linux source package in Disco: Incomplete Status in linux-meta-hwe source package in Disco: New Bug description: Node "amaura" cannot be deployed with Bionic / Cosmic / Disco image.

BTW, I can see some RAM related messages probably indicates a hardware issue, not sure if it has something to do with that.
