System hangs on reboot/shutdown after kernel upgrades

I've been experiencing the problem that, whenever pacman upgrades the kernel, the system hangs on reboot or shutdown.  It only happens on the first reboot/shutdown after a kernel upgrade.  I've noticed it consistently for a while now.

To reboot, I issue:

# reboot

To shutdown, I issue:

# shutdown -h now

I should also mention that I typically reboot after kernel upgrades because hotplugged storage devices (USB, SD) fail to be detected unless the system reboots.  That is, devices plugged in during the upgrade remain usable, but plugging in something new appears in /dev.  There may be an obvious reason for it that I'm missing, but it's never bothered me enough to look into it.  Not sure if this and the reboot/shutdown issue are related, though.

Any ideas would be greatly appreciated.  Thanks!
