2.6.21.4: general protection fault: 0000 [1]

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 
While trying to copy a file from my cell phone to a ext3 partition over bluetooth ( with gnome-vfs-obexftp 0.2 using bluez-utils 3.7 ) I got two 'general protection faults' in my vanilla 2.6.21.4 kernel ( tainted with NVidia module ) 

This appeared in the console:
