Hi, I'm running m5.fast for X86_FS and couldn't resume a checkpoint. The linux kernel is 2.6.30.5. The command I used was "build/X86_FS/m5.fast configs/example/fs.py -r 1". The checkpoint was dumped from a previous run, after the system just boot.
The simulator side goes like: =============================================================== M5 Simulator System Copyright (c) 2001-2008 The Regents of The University of Michigan All Rights Reserved M5 compiled Apr 11 2011 17:49:05 M5 revision Unknown M5 started Apr 12 2011 15:16:06 M5 executing on MACHINENAME command line: build/X86_FS/m5.fast configs/example/fs.py -r 2 Global frequency set at 1000000000000 ticks per second info: kernel located at: MACHINEPATH/binaries/vmlinux-2.6.30-x86_64 Listening for pc connection on port 3456 warn: Reading current count from inactive timer.

For more information see: http://www.m5sim.org/warn/7fe1004f =============================================================== and the console side prints: =============================================================== do_IRQ: 0.36 No irq handler for vector (irq -1) do_IRQ: 0.36 No irq handler for vector (irq -1) do_IRQ: 0.36 No irq handler for vector (irq -1) do_IRQ: 0.36 No irq handler for vector (irq -1) do_IRQ: 0.36 No irq handler for vector (irq -1) do_IRQ: 0.36 No irq handler for vector (irq -1) do_IRQ: 0.36 No irq handler for vector (irq -1) do_IRQ: 0.36 No irq handler for vector (irq -1) do_IRQ: 0.36 No irq handler for vector (irq -1) do_IRQ: 0.36 No irq handler for vector (irq -1) =============================================================== then everything stays still for a very long time and exits. I'm thinking whether this has anything to do with the linux kernel. Does anyone have similar experience and possibly a solution? I'm digging into it but it would be nice if someone have solved this before. Thanks, Feng
