FYI, we noticed the following commit (built with gcc-7): commit: 97ca70e16dc76bad69ad774cf0bd0286c97d63b4 ("compat_ioctl: scsi: move ioctl handling into drivers") https://kernel.googlesource.com/pub/scm/linux/kernel/git/arnd/playground.git to-build in testcase: mdadm-selftests with following parameters: disk: 1HDD test_prefix: 06 on test machine: qemu-system-x86_64 -enable-kvm -cpu SandyBridge -smp 2 -m 4G caused below changes (please refer to attached dmesg/kmsg for entire log/backtrace): If you fix the issue, kindly add following tag Reported-by: kernel test robot <rong.a.chen(a)intel.com&gt;

Welcome to fdisk (util-linux 2.29.2). Changes will remain in memory only, until you decide to write them. Be careful before using the write command. Device does not contain a recognized partition table. Created a new DOS disklabel with disk identifier 0x8b600b10.

I don't immediately see where my patch went wrong, so I tried to reproduce the steps below, and ran into multiple problems with the job script:

1. /osimage/deps/debian-x86_64-2018-04-03.cgz/mdadm-selftests_2019-06-26.cgz could not be found on the server. I tried replacing it with mdadm-selftests_2019-04-29.cgz, which seems to be the latest version on in that directory.

2. -cpu SandyBridge did not work for me, as I'm on an AMD machine. I used "-cpu host" instead.

3. error "qemu: linux kernel too old to load a ram disk". I tried leaving out the initramfs, knowing that this would finally break things if I still had a chance of reproducing the bug at this point. 4. qemu-system-x86_64: -append root=/dev/ram0: Could not open 'user=lkp': No such file or directory. No idea. I tried removing this. 5. Could not open 'job=/lkp/jobs/scheduled/vm-snb-4G-55ee9590a4b9/mdadm-selftests-1HDD-06-debian-x86_64-2018-04-03.cgz-97ca70e16dc76ba-20190728-5974-13wd49f-3.yaml': That directory does not exist, and I could not find the file elsewhere. Any suggestions?
