Public bug reported: Description A customer reporting ACPI errors during Linux boot in an 8 socket glueless system with 6 DCPMM modules installed per socket. After OS has completed initialization, any attempt to use NDCTL or IPMCTL results in a process or system hang. The system boots and the apps are ok when reducing the system configuration to 6 sockets. Log extract is below.
A web search turned up what looks like the same problem. See https://lkml.org/lkml/2019/5/30/1290. This link describes a kernel change to increase the dimensions of the failing table. Your names appears in the signed-off of this link Can you confirm if it is the same problem described below (it looks like it is) and if the proposed kernel change describe in the link is the correction? Customer has checked kernel.org and the latest versions of the affected files do not have kernel change. They are validating RedHat and Suse Enterprise for 8+ socket system with maximum DCPMMs installed. Are there other items that must be updated to go along with the kernel change? These messages are extracted from the start-up log showing the OS and Kernel versions plus the ACPI errors.
