I suppose if I could be certain about how to compile bootblocks, I might be able to do something on the serial console with a laptop. But the one time I attempted that was a disaster. Is my speculation about the "...no dump device found..." correct? Is it that swapon and multiuser has not occurred, and so there can occur no dump to the swap space? > Probably someone is accessing a NULL pointer. If any more damage occurs, ISTM that my entire installation will be accessing a NULL pointer; the following message is from the most recent dmesg, and is new: warning: KLD '/boot/kernel.old.bootable/drm.ko' is newer than the linker.hints file Since my hardware appears to not work with the available source, who knows how that will go?
