I'm trying, but I can't get a crashdump. I have dumpdev in rc.conf

but doing the math it should fit.
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...)
Memory corruption: by adding or removing options, you change the kernel
itself as well as its behaviour. This can change where in the kernel
the corruption happens and what sub-systems are being affected.
See if some other options have the same effect...
