Hi, Mr. Guenter,
Thank you kindly for your reply.
I agree with you that it adds a lot traffic to the channel with little "signal" when compared to the "noise".
However, there is about a 100 such warnings from 26 modules, and I do not feel competent and equipped to
analyse all of these:
1 arch/x86/entry/common.c
1 arch/x86/kernel/apic/apic.c
4 arch/x86/kernel/cpu/mtrr/amd.c
1 arch/x86/kernel/cpu/mtrr/centaur.c
1 arch/x86/mm/pat/memtype.c
13 arch/x86/mm/pgtable.c
1 block/blk-merge.c
1 drivers/firmware/efi/libstub/efi-stub-helper.c
8 drivers/hwmon/aht10.c
2 drivers/hwtracing/intel_th/core.c
10 drivers/hwtracing/intel_th/msu.c
17 drivers/memstick/core/memstick.c
2 drivers/pinctrl/pinctrl-aw9523.c
2 drivers/tty/n_hdlc.c

2 kernel/time/tick-broadcast.c
5 lib/842/842_compress.c
4 lib/842/842_decompress.c
1 mm/page_counter.c
