Not sure if do you have a "dc" or "sis" interface in your system, by chance ? I used to get a panic on reboot, in a previous version of the code, which disappeared when i introduced the check for IFF_RUNNING before invoking xx_poll() on the device. If it happens again, please let me know, maybe together with the list of interfaces you have. (I notice that the original code in dc_stop() and sis_stop() is slightly incorrect, because it first frees resources and then marks the interface as not RUNNING. This might lead to a race and explains the panic and why it does not happen all the times). cheers luigi ----------------------------------+----------------------------------------- Luigi RIZZO, luigi@iet.unipi.it .
