Following kernel BUG noticed while running perf testing on qemu-x86-64.
Thanks Naresh. I'm aware of the crash[1] but haven't got a chance to root cause it. Let me try to spend some time on it.
I tried to mimic https://lkft.validation.linaro.org/scheduler/job/5708609. However, I don't see a way to download lava-guest.qcow2. So I just used rootfs and kernel:
/usr/bin/qemu-system-x86_64 -cpu host -enable-kvm -nographic -net nic,model=virtio,macaddr=DE:AD:BE:EF:66:20 -net user -m 1024 -monitor none -kernel bzImage --append "root=/dev/sda rootwait console=ttyS0,115200" -hda lkft-console-image-intel-corei7-64-20221019172733.rootfs.ext4 -m 4096 -smp 4 -nographic
And I ran perf test inside the guest, which ran fine.
Would it be possible for you to redo the experiment and see if you are able to reproduce it consistently.
Thanks, Ravi
