When can I call kthread_create? I tried in the driver attach, but that failed in fdcopy() calling vref with a NULL pointer. I tried calling at the end of config (in config_intrhook_establish called function), but no dice. I see that this makes its calls at SI_SUB_INT_CONFIG_HOOKS (0xa800000 in init sequence). I'd like to run it before SI_SUB_COM_ROOT_CONF, but it doesn't look like I could call it until SI_SUB_KTHREAD_INIT, which is too late to allow an insert event to happen to allow a root device to be in a pccard/cardbus (well, I could poll the device in attach routine if I'm not already doing this, so that restriction might not be a big deal). Is this analysis accurate? Do I have to wait until at least SI_SUB_KTHREAD_INIT? Or is INIT special and I'd have to wait until after all the "special" processes are created? Thanks for your help in this matter. Warner To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
