I have an SD-card in our embedde= d device (AVR32 AP7000). Some random data is continuously written to an =46AT 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 bu= t I will give it a try. regards Andreas Bie=DFmann -- To unsubscribe from this list: send the line "unsubscribe linux-fsdevel= " in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html
