You would need to figure out which processor / device generated this
address and why. You can start with collecting the trace starting some
time before the cycle mentioned in the panic message below.

Hi,
I am trying to simulate O3 CPU in FS mode, without ruby. However, the
moment I specify more than 1 cores, i get the same error as mentioned in
this thread. Any idea about how this could be resolved ?
**** REAL SIMULATION ****

I have booted with 2GB of memory. Any thoughts ?
Thanks for your help.

Even though full system simulations have been allowed with O3 CPU and
Ruby, it may not necessarily work out right now. We are still discussing
some patches about the O3 CPU which may improve the situation.

Hi,
I'm trying to use O3CPU and Ruby FS config in gem5 but before linux boots
up completely, I get following panic:
"panic: Unable to find destination for addr 0x100000008
@ cycle 172076977000
[findPort:build_alpha_fs_**moesi_cmp_dir/build/ALPHA_FS_**
MOESI_CMP_directory/mem/bus.**cc,
line 359]
Memory Usage: 3951952 KBytes"
This happens in I/O section of the bootup. Following are the last few
lines
in system.terminal:
NET: Registered protocol family 16
EISA bus registered
pci: enabling save/restore of SRM state
SCSI subsystem initialized
I tried to run making flag use_default_range = False but that gives panic
at some other place.
I'm using linux kernel available on website and I increased memory size to
3GB.
Is O3CPU+Ruby FS stable gem5 config to use?
Is it a known issue?
I'd appreciate any help on this.
Thanks,
Ripudaman Singh
