I had an occurance of an FC3 system apparently locking up when a USB KVM was switched back (via keyboard hotkey sequence) so that the FC3 system was the currently selected one. At the time I had the ogg audio player running, and when the KVM switch occured the sound got stuck in an infinite looping pattern, about 3 repeats per second. The system was otherwise dead..black screen, no network response, no alt-hotkeys responsed. I suspect a kernel lockup, but have no real proof. I mentioned the audo player as a possible point of conflict, because I've never had problems without it running. Also I noticed on a few of the KVM switches the audio would stutter. The system was otherwise idle except the audio player, and the audio typically never stutters on this system. I have a USB keyboard and a USB mouse (not PS/2) which the KVM switches along with the audio. It is an IOGear 2-port mini USB. The system is a single CPU Athlon 800 MHz, running FC3, all updates, with kernel 2.6.12-1.1372_FC3. Does anybody have any idea what may have caused this, or what I might do to be prepared if it happens again so I can help diagnose it? -- Deron Meranda
