/var/log/messages displays kernel warning messages
in servers with NVDIMM-N persistent memory
modules
Description:
The following kernel warning messages are observed in dmesg and /var/log/messages on servers with
NVDIMM-N persistent memory modules connected:
kernel: nd_region region1: scrub start while range 1 active
kernel: WARNING: CPU: 14 PID: 14705 at ../drivers/acpi/nfit/core.c:3189
acpi_nfit_scrub+0x37b/0x3a0 [nfit]
This is a cosmetic issue and does not affect functionality. The warning message that is displayed can be
ignored.
Applies to: SUSE Linux Enterprise Server 15 Service Pack 2 and later.
Cause: The warning message is observed due to a race condition between the BIOS and operating system
initiated address range scrub operation.
