It looks like your system has:
- Kernel crash dump configured.
- Something is causing crash while you issue a reboot, may be some module unload path has a bug.
- Crash is triggering kernel dump to take dump of memory (I guess you have plenty of RAM to justify 45 minutes) in /var/core directory. Although dump image is highly compressible but compression is the last step.
- If there is no space in /var/core, kdump gives up and you see faster reboot.

Do you have any clue at all where in the reboot process it's sitting
for the 45 minutes?
