I let my SMP box run overnight. WHEN there was a crash when writing CF (perhaps every 2 weeks or so), THEN I got sometimes BIG problems with writing even after a reboot - locked up again immediatly. IIRC my workaround was to remove the modules and load them again before using them. Yes, sounds weird. I tried to analyse the problem but gave up. I used usb-uhci on 2.4.9 to 2.4.18-SuSE
