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
