Vmware2 stopped running from both md and ad devices. Virtual disks still work. It is caused by a read that is not on sector boundary. Should a program be able to read non-sector sized chunks from a raw disk yes or no? What is the desired behaviour? The fact that this did work, was it a bug or did this come out due to some other change. The stacktrace from read(2) is below. Any input welcome, it's about time that vmware runs again on -current.
