It was sys/dev/pci/pci.c rev.1.141 which triggered it. Stack use must already have been tight, and the additional device number array was the last straw. The question is now whether it is sufficient in the long run to trim down stack usage (eg "devinfo" in ppbattach()), or whether the kernel stack needs to be increased. > Please revert the reversion. I will add a big, fat comment. It makes more sense if you commit the code together with the comment, and "cvs annotate"'s output would be more sensible too. best regards Matthias ------------------------------------------------------------------------------------------------ ------------------------------------------------------------------------------------------------ Forschungszentrum Juelich GmbH 52425 Juelich Sitz der Gesellschaft: Juelich Eingetragen im Handelsregister des Amtsgerichts Dueren Nr.
