Hello, using the suspend function, when I awake the desktop, the usb
mouse non longer functions.
have a PS2 keyboard so was able to qvm-kill sys-usb and do qvm-start
sys-usb but it complained couldn't connect to qrexec or so and failed.
so qvm-start sys-usb a 2nd time and then the mouse functions again
is this to be expected, or is there something to fix ?

went to the URL says something like I should be "enable CPU buffer
clearing"
but can't find how to do that, curious if it's actual needed ?
....moral of the story don't suspend your qubes desktop ?
.....any idea on the "data leak possible" journal entry?
sounds a bit scary, maybe I need to look around in my UEFI to disable
some cache-ing ?
BTW, kudos to qubes team for the dom0 copy to clipboard widget , sure
makes it easier to get dom0 notes out !
