linux-odroid-xu4-4.14.16-1 one core at 100%

Postby MrL » Sat Feb 03, 2018 9:14 pm

Hello forum,
after upgrading my XU4 CloudShell 2 to the linux-odroid-xu4-4.14.16-1 kernel one core runs always at 100%. After downgrading back to 4.14.15-2 this problem was gone.

I checked again and upgraded to 4.14.16-1 again and again one core runs at 100% infinite.

I'm not sure if this is a specific CloudShell 2 problem or generally on XU4.

Did someone else face the same issue and what should I do? Simply wait for the next kernel release and check again?

Best wishes,
Mr.L

Hi, I'm having the same issue on an XU4
I've noticed due the fact that my fan is running more than usual. Running 'top' I've found this:

PID USER PR NI VIRT RES %CPU %MEM TIME+ S COMMAND
265 root -51 0 0.0m 0.0m 99.3 0.0 295:06.36 R `- irq/153-ads7846

It seems that is caused by the module ads7846, so unloading it will fix the issue.

It shouldn't happen anyway...

Yep, blacklisting the ads7846 module solved the issue.
