It has been doing very well, except for this scenario. The wireless interface wlan0 is busy communicating, and the power is disconnected abruptedly. In the next boot, we get a kernel panic when the wlan interface is initialised. We want to know if this is due to linux's journaling file system (we are using ext3)? Does it keep track of the state so closely, even up to the point of the previous abrupt shutdown? If so, what can we do to "cleanup" in the next boot to avoid the kernel panic? Regards Keith
