Can't seem to trip the issue on a 24 core x86 instance, maybe this is ARM64 specific. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/2038768 Title: arm64: linux: stress-ng filename

I created a 1GB file and created a fresh ext4 file system on it and loop back mounted it on /mnt, I created test directory /mnt/test and ran: /stress-ng --filename 0 --temp-path /mnt/test --klog-check Managed to trip the kernel crash again. So it appears to occur on a fresh ext4 file system

Note that just running stress-ng with --filename 0 will reproduce the issue. I'm testing this now on a cleanly formatted ext4 file system -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu.
