You can try to boot the installer under kmdb control, by appending
option "-k" at the end of the grub "kernel" line.
When the installer hangs, you can break into kmdb by sending
a BREAK signal on the serial line.
In kmdb you can try the command "::ptree" to view what
processes are currently running. "::cont" resumes the kernel.
You may wait a minute, repeat the BREAK, ::pstree, ::cont a few
times, and check if the list of running processes changes.
Other commands of interest in kmdb might be
::cpuinfo -v
::memstat
::kmastat
::arc
(zfs' arc cache might have problems with the kernel's heap,
that's why ::memstat, ::kmastat, ::arc could be interesting; but
that's just a wild guess by me...)
