Hi Gerd,
2.9 seems to have an xhci migration breakage, I've bisected it
down to:
commit ddb603ab6c981c1d67cb42266fc700c33e5b2d8f
Author: Gerd Hoffmann <[email protected]>

xhci: don't kick in xhci_submit and xhci_fire_ctl_transfer
I guess maybe there's a kick needed pre/post migrate?
(it's https://bugzilla.redhat.com/show_bug.cgi?id=1436616 )
The symptoms on the destination are that the qemu prints:
qemu-kvm: usb-msd: Bad signature 53425300
and the guest sees:
xhci_hcd 0000:00:06.0: WARN Event TRB for slot 1 ep 0 with no TDs queued?
xhci_hcd 0000:00:06.0: WARN Event TRB for slot 1 ep 2 with no TDs queued?
xhci_hcd 0000:00:06.0: WARN Event TRB for slot 1 ep 3 with no TDs queued?
and never gets any more IO on the USB disk.
Any ideas?
Dave
