kernel warnings on dmesg

Unread post by alvarow » Thu Oct 17, 2019 11:39 pm

Hello, I keep getting kernel warnings on my N2... It is powered by the power brick, not USB and it only has a USB3 powered external drive connected to it. Right off boot it prints the below, it has been happening for a while, last few kernels up to 4.9.196-63

Anyone else experiencing it?

Re: kernel warnings on dmesg

Unread post by joshua.yang » Fri Oct 18, 2019 9:53 am

Hi.

I'll try to reproduce that issue. Before that, I have some questions to make the test condition clearly.

What kind of external drive? Is your drive HDD? It will be appreciated if you let us know your drive product name.
Did you mean directly connection between a USB external drive and N2 without a USB hub?

It is a WD Elements 10TB HDD powered drive, connected directly on the N2, no other USB devices connected, connectity is via ethernet port... I can't tell of any problems, the N2 seem to work and behave fine, aside those ' [ cut here ] ' messages.

Sorry for the late reply.

What kind of jobs could occur that message?
That message shows even on simple dd jobs like dd if=/dev/sda1 of=/dev/null?

And could you let us know the results of the lsusb and lsusb -t?

This happen when you use cpufreq governor and cpufreq still very unstable the last time I check. Use performance or interactive instead.
