Here is something really odd: For debugging I had options KDB options DDB options GDB in my kernel conf. To find out why it would not dump, I removed DDB and GDB, and now it has gotten a lot harder to panic the system. If I plug or unplug the USB drive slowly, I get the usual connect/ disconnect messages and no panic. Only when I connect and then around 3 s later unplug, I get a panic. This is while the connect message comes by on the screen. (Ok, maybe I'm asking for it at that point.) How could the inclusion of DDB/GDB affect the USB subsystem? Some odd timing problem? (And still no way to create a crashdump...) With kind regards, Ben
