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.
