While running the regression tests while at master commit 68af229490fc811aebddf68b3e2e09e63a5fa475, one of the tests failed with the following output: --- quick/fs/10.linux-boot/arm/linux/realview-simple-atomic-checkpoint --- *** gem5: ERROR: gem5 exited with non-zero status: 1 gem5 exited with non-zero status: 1 *** gem5 stderr ***

I've then updated head to the following commit (0473286ab1e9992a906eff380000bf90c82eeccb), and the same test passed. As it also passed using a commit that has still not been rebased to 0473 (https://gem5-review.googlesource.com/c/public/gem5/+/8501), they were likely lucky runs. Hope this is useful for the maintainer. Att,Daniel _______________________________________________ gem5-dev mailing list [email protected] http://m5sim.org/mailman/listinfo/gem5-dev
