O, God! Kernel panic when extracted MSDOS device without unmounting them exist in FreeBSD till 2.2.5 version *ROFL* That ancient days, when you mount floppy and extract without unmounting, kernel panics... This days flopies were dead. But their place now occupied by USB Flash drives, which you can easily extract without unmounting. And "I'll back" :-) - when you extract mounted flashdrive, kernel panics again... For me, USB subsystem in FreeBSD works terrible. Inserting USB Flashdrive can hang up or reboot system, inserting digital camera can freeze system until USB cord will extracted, boot with inserted USB Flash dumps BTX "registers over", USB wireless mices, bought with wireless keyboards, does not works... It's too sad... -- With Best Regards. Rashid N.
