I have an SD-card in our embedded device (AVR32 AP7000). Some random data is continuously written to an FAT filesystem on that device. When you pull the card out of the slot you trigger that NULL pointer dereference. I will try to reproduce that error on my workstation but this will need some time. Maybe I can not hit that race on my quad core workstation but I will give it a try. regards Andreas Bie?mann -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
