Status in linux package in Ubuntu:

Bug description:
  I use Ubuntu 19.10 AMD64 (completely up to date) on a Lenovo Thinkpad S1 Yoga 
12, and I've just noticed that /var/log/kern.log is flooded by messages like :
  Nov 30 21:12:44 yoga kernel: [  526.471259] ACPI: \_SB.PCI0.LPCB.EC0.ECRD: 1 
arguments were passed to a non-method ACPI object (RegionField) 
  Every about two seconds, 18 messages of this kind are recorded.
  What could I do to provide more informations ?
