Comment 16 for bug 1766201

Update: the patch to downgrade the error "Unable to open file..." to a warning seems to be already applied to the bionic kernel (https://git.launchpad.net/~ubuntu-kernel/ubuntu/+source/linux/+git/bionic/commit/?h=master-next&id=58441dc86d7b066a2c02079829a96035587a7066) and the cosmic kernel (https://git.launchpad.net/~ubuntu-kernel/ubuntu/+source/linux/+git/cosmic/commit/?h=master-next&id=ed79083b0d87cef2a64f906614f49faa40337e96).

About the other "uevent" errors, do you think it would help to provide a test kernel with some little extra instrumentation to track down the userspace task that is (apparently) sending incorrect data via sysfs (i.e., adding pid, name, etc. to the error message)?
