I believe the qcam driver has changed a couple of weeks ago. Some new code has been introduced and made things worse. I didn't check the cvs repository for that but I seem to remember. On a machine in the campus - blues, a 486DX2/66 - the kernel qcam driver doesn't show these timeouts and also doesn't lock the system every second or so while in my town office I have Amd5x86 DX4/133 which should be faster but since it's running a Sep 1 kernel it has this nasty behaviour. Maybe one should backout the qcam driver changes?
