Has anyone else seen something like this? I just performed 3 more
4.5-RC3 installations with varied installation parameters but I was
unable to cause a failure. If you're lurking on this list looking for
a way to contribute, please pull down RC3 and let us know if you can
corroborate Jordan's phantom-bug.
Thanks,
- Murray

Unfortunately, this one seems to be in the "heisenbug" category which
is why I didn't flag it as a show-stopper when it started getting
reported by others in -stable, referring to the 4.4-snapshot releases
they were installing from ftp://stable.freebsd.org/pub/FreeBSD.
I don't know when/how it crept in, but there now appears to be a bug
which manifests itself during sysinstall's distribution extraction
phase, always while installing the src distribution (my canonical
installation profile for testing developer installs is X-developer).
I also believe it's actually a kernel panic or hard hang vs sysinstall
croaking because no signal is caught and the kernel does not panic
with "init died" - the system simply hard hangs and you can't switch
VTYs or interact in any way with the system. Just to make this even
more annoying, the bug does not seem to manifest itself if you have
Debug mode selected or are on VTY2 when the crash happens. I'm still
pursuing a 100% reproductible test case, but it's an evil problem.
