Flashes (Alerts)
Abstract
When extra memory is added to a running Linux logical partition (LPAR), the partition might crash. This issue is observed whenever memory is added after a removal of some amount of memory at run time.
Content
Linux® releases affected: Red Hat Enterprise Linux 8.2, or later
IBM systems affected: All IBM POWER8®, and later systems that are based on PowerVM®.
Symptoms
The kernel crashes with an assertion that is similar to the following:
kernel BUG at mm/memory_hotplug.c:1116
Where, 1116 is a line number that can vary across kernel versions.
Workaround
If memory is removed since the partition has last booted, do not add memory to a running partition. Restart the partition before you add memory.
