Check the %wa field in top - most likely the CPU is busy with some I/O
accesses (probably the HD).
I always look at the %id to get the % CPU amount actually used because
%wa is not added to %system or %user

Instead of power cycling, use REISUB - it should be easier on your file
system (need to enable it with "kernel.sysrq = 1" in /etc/sysctl.conf)
