 Hi,
 
 If you add the kernel debugging options to your GENERIC file, then you will 
 get a backtrace next time it crashes.
 
 There is also a script under:
 /usr/src/tools/regression/usb/
 
 Which you can use to forcedly re-enumerate your USB card-reader. Try that when 
 a card is inserted with NTFS and see what happens.
