How do I find out the stuck process leading to this extra load ?
try atop. I find it gives a lot of extra information about processes
Hum, compared to a normal 'desktop' box, it list one process
as being in #tslpu state, i.e. sleep ininteruptible, and I wonder if
that's what is accounted for it. There is basically only 2 processes
active in the system: atop and ksoftirqd/0 which is basically the
kernel interrupt handler (well there is also ssh but it usually doesn't
even shows up).
The process in D state is apparently a kernel usb thread
root 18 0.0 0.0 0 0 ? D Jan16 0:00 [usb-hardware-sc]
it is present in that state on both boxes (no USB device connected, but
if I plug mouse or keyboard they work just fine).
Interesting. I'm seeing the same issue on 1 of my a10 devices, but not
on another (and I have yet to try the rest). The one which exhibits the problem
also has issues connecting to wifi (it contains an usb wifi adapter like most
A10 devices).
I'll investigate this further.
Regards,
Hans
