I upgraded to Fedora 19 (from F17) and rebuilt kernels.
I rebuilt some kernels, found the fix to the encrypted swap activation
issue, etc.
I'd have to look up the date, but around july 14th?
Due to unfortunate changes in systemd I could not boot older kernels
anymore in F19 and needed that swap fix (remove /sbin/hotplug helper
definition). 3.9.9 is oldest one that boots but shows the issue(s).
I am now rebuilding 3.8.5 to see if that makes a difference for any of
these issues.

First alone the USB issue was present, later the PS/2 issue started but
(stupidly) I failed to note the kernel version. (or date) (but it was
post F19 migration)

I did not find any stuff in /var/log/messages that correlates with the
'ps/2' issue. (ps/2 as that is the interface of my keyboard but the
source could be elsewhere)
I will retest if the ps/2 issue is also present without keyboard connected.
I will see if the ~2 day delay from boot is consistent with the issue
occurring.
