I send some more information to phk this very early morning. The problem seens to be that none of the classes has a goem entry when going through g_valid_obj(). Another thing that crossed my mind while going to work this morning is that the only related reports I had seen are when mounting rootfs. [ also see 5103.1068811352@za.uu.net , this month in current ] What about the atapi-cd case ? From the debugging this night I remember that there are some XXX comments in geom_dev about this. Just another thing one might keep in mind while further debugging. -- Bjoern A. Zeeb bzeeb at Zabbadoz dot NeT 56 69 73 69 74 http://www.zabbadoz.net/
