    I've made a number of fixes to amd64 kernel dumps in -current
    and it's all working for me now.  is it working for you too?
 Well, I just hit a panic on that machine...and (although the stack
 trace from ddb that I caught flying by on the serial console was
 enough to debug the problem) it didn't even make a kernel crash dump
 dump Skipping crash dump on recursive panic
 panic: wddump: polled command has been queued
 Since I'm about to be messing with that machine's kernel and rebooting
 anyway soon, I'll try and elicit a core dump with a newer kernel and
 when it's not under the heavy load of a pkgsrc bulk build.
