I had the same issue with an X1 at work, disabling USB with boot -c or
config would eliminate the problem.
Thanks Nick,
That is it. So, that's where the issue is.
I tried on a few systems, X1 or V100 and disabling it does fix this
error by one.
Now is trying to find exactly where the might be next.
It's been over 6 months since I worked on this, and I won't be able to
verify until Thursday, but I recall leaving usb enabled, but keeping a
USB device such as a mouse or RS232 adapter plugged in would also bring
the load back to 0. Seems like the load could go back up 1 once I
unplugged the device, but it's been a while.
That plug, unplug, I didn't test it as all my systems are remote, but I
will try it and see. Might be a way to find the bug.
I assumed it was buggy USB hardware causing something usb related in the
kernel to block on IO and raise the load by 1.
May be. The only thing I know is I saw a few exchange on the list where
usb sure is not thought of as being so great at times. If I remember the
name right, I saw a few comments from Henning as well not always be
gentle to USB design. (;>
Hopefully this gives you something to go on.
Will see if any progress can be done form here.
Thanks
Daniel
