grepping for `ioctl' gives:
ioctl(9, SIOCGIWNAME, 0xbfe38d8c) = -1 EINVAL (Invalid argument) ioctl(9, SIOCETHTOOL, 0xbfe38d2c) = 0 ioctl(11, SIOCGIFHWADDR, {ifr_name="eth0", ???}) = -1 ENODEV (No such device) ioctl(11, SIOCGIFFLAGS, {ifr_name="eth0", ???}) = -1 ENODEV (No such device)
Perhaps you could generate the strace output for 2.6.18-rc5, grep that for ioctl, look for differences? That initial SIOCGIWNAME failure is fishy. - 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/
