I agree not to revert back at early 2018 revisions.
I checked out on 059122e22b3651cd7cb3d6581176c745c64cbe8e, which is the pointed commit (https://gem5-review.googlesource.com/c/public/gem5/+/19449) and the assertions disappered.

Thank you both.

Best regards,
Michail

Hi Michail,

I wouldn't advise going back. I think we fixed this (at least one path
leading to this issue) in the following patch:
https://gem5-review.googlesource.com/c/public/gem5/+/19449

Please test it and let us know if your issue presists.

Best,

Hello all,

I am using gem5 revision commit
4c38c7c02aca9922d7f30f2f399bbe94c034eb59.

I try to run a full system emulation, after restoring from a
checkpoint
and using standard-switch option, in order to run over DerivO3CPU
cpu
model.

I use the following command:
./build/X86/gem5.opt -d /tmp/gem5_test --stats-file=test.csv
configs/example/fs.py --checkpoint-dir=/tmp/cpts/benchamark
--checkpoint-restore=1 --caches --l2cache --maxinsts=3200000000
--standard-switch=3000000000
--kernel=/home/gem5/binaries/x86_64-vmlinux-2.6.22.9
--disk-image=/home/gem5/disks/ubuntu-14.04.img ;

The result is that, there are some cases (different checkpoints/
benchmarks) where I get the following assertion:
build/X86/mem/packet.hh:1094: T* Packet::getPtr() [with T =
unsigned
char]: Assertion `flags.isSet(STATIC_DATA|DYNAMIC_DATA)' failed.

Is this a known issue?
Should I modify the command above?

Thank you
