It is not serious but rather annoying.
Thank you. Good to hear it is not critical. I would ignore the messages, but it is annoying that almost 4MB of log messages are generated on every resume after standby. Maybe it is possible to define a limit for the maximum amount of the same messages?

Currently I am using BIOS v1.22. Recently Acer released v1.23. I could test if the BIOS update solves the problem.
