I looked at all the isa drivers that use M_WAITOK and there seems to be a problem in them all. Some of them bogusly check whether the waiting malloc() returns 0 and could probably be fixed easily by switching to a non-waiting malloc(). There aren't many isa drivers with the problem so fixing it should be manageable especially if it is acceptable for open() to return ENOMEM. Brucehome | help
