Cascardo, Alan,

Bringing back that old thread..

I'm trying to kexec from our OPAL FW bootloader (3.10.23 based) to a
fedora 3.14.3 on a new machine and am still seeing the above.

A reset brings the chip back.

Do we have any resolution here ? It looks like the xHCI remains active
on the way out and is clagged up on the way back in, at least in a
state the driver really doesn't like.

And this is a "clean" kexec, not a forced one... This is killing USB on
the upcoming OpenPower dev machines.

Cheers,
Ben.
