I made the following change to the config file for the fs regression test. After that I just ran the command line from the simout file for this regression test.

Hi Nilay,

I cannot reproduce this failure.  The only regression test for
X86_MESI_Two_Level uses a simple timing CPU, so that passes OK, as do all
the other regressions, even when this is the only patch applied.  I tried
this command line:

   build/X86_MESI_Two_Level/gem5.opt configs/example/fs.py
--cpu-type=detailed --caches --ruby

and the simulation appears to hang after printing this on the console:

   ACPI Exception (tbxface-0618): AE_NO_ACPI_TABLES, While loading
namespace from ACPI tables [20070126]
   ACPI: Unable to load the System Description Tables

but I do not get a segfault as you have indicated.  Can you tell me exactly
what command line you were using to observe the error?

Thanks,

Steve
