o Lock ed o Fix extra newline in probe messages o Eliminate gone. o Make detach less-racy. o Eliminate spl* o Switch from timeout/untimeout to callout interface. o Read/write card memory using bus_space calls. o generalize readmem so that we don't need ifs in the code. o Fix memory stuff to be consistant. o Remove OLDCARD compat stuff. o Mark interrupt as MPSAFE. # sic, hpp not tested at all # ISA and PCI attachments lightly tested
