Hi,

 

Looks like kernel config CONFIG_USB_STORAGE_DEBUG=y has been set in the Debian Jessie 4.0.4 build. That means, that when I have I/O to a usb-storage device, systemd-journald is consuming ~70-90% CPU time on consuming debug log lines from the kernel.

 

Is this by purpose? How would I be able to filter or disable all this log content from the kernel to journald?

 

Yes, I noticed few days ago ... I was doing some extensive config merging and it came inside by mistake.

Thanks.

 

In the mean time you can use this kernel. Fixed and built yesterday.

Thanks!

 

That orangepi-next kernel, will that actually work on the cubietruck btw.?

Yes, kernel is the same.

Perfect, I just tried the orangepi-next kernel. It works and usb-storage-debug is disabled again. Thanks for your help!
