== Comment: #0 - D. Gary Chapman <chaps@us.ibm.com> - 2022-01-26 12:43:25 ==
---Problem Description---
IBM IDAA customer exposes hypersocket page allocation failure on Ubuntu 20.04 based SSC
Contact Information = Gary Chapman (chaps@us.ibm.com)
---uname output---
5.4.0-73-generic #82-Ubuntu
Machine Type = IBM Z in IDAA SSC-mode lpar
---Debugger---
A debugger is not configured
----------
IBM SSC LEVEL: 4.1.5
IBM IDAA LEVEL: 7.5.6
On a client system we are observing this:
Jan 19 16:25:57 data5 kernel: kworker/u760:28: page allocation failure: order:0, mode:0xa20(GFP_ATOMIC), nodemask=(null),cpuset=/,mems_allowed=0

IBM LTC Networking team has identified the upstream commit 714c9108851743bb718fbc1bfb81290f12a53854 as the root cause.
This patch shows up in the Ubuntu kernel source tree:
