If I'm remembering correctly this is a bug that was introduced when
curTick was changed from a global variable to a function. It should be
fixed in the latest version of the code. The checkpoint files are
basically just text, so if the new code is looking for something other
than curTick (I'm not sure if it will or not) you should be able to
adjust it pretty easily.

Hi,
I took checkpoint of M5 in FS mode. But when I try to load the checkpoint,
it fails with the following error :
-----------------------------------------------
fatal: Can't unserialize 'Globals:curTick'
@ cycle 0
[paramIn:build/ALPHA_FS/sim/serialize.cc, line 211]
-----------------------------------------------------------------------------
I took checkpoint using following command :
----------
./build/ALPHA_FS/m5.opt -d /scratch/l configs/example/fs.py -n 4 -b fft
--take-checkpoints=2438845340000,1000000 --max-checkpoints=1
----------
And when try to load the check point I get the following output :

Any ideas on where the problem is?
