Subject: [bug report] nvme: fio workload hangs on 16m random read
Date: Thu, 06 Mar 2025 21:46:37 +0100 [thread overview]
Message-ID: <87a59x6g5u.fsf@kernel.org> (raw)
Hi All,
My CI system has found an issue for the following fio workload:
root@debian:~# insmod /mnt/v6.14-rc5-build/drivers/nvme/host/nvme-core.ko
root@debian:~# insmod /mnt/v6.14-rc5-build/drivers/nvme/host/nvme.ko poll_queues=1
"fio" "--group_reporting" "--name=default" "--filename=/dev/nvme0n1"
"--readwrite=randread" "--blocksize=16777216" "--direct=1" "--numjobs=1"
"--ioengine=io_uring" "--iodepth=1" "--hipri=1" "--time_based=1"
"--runtime=3000"
fio will hang, some times immediately, some times after a few minutes.
I observed this on v6.14-rc1 and v6.14-rc5. It is not present in v6.13.
Can any of you reproduce this? I was able to reproduce this on real
hardware and in qemu.
Best regards,
Andreas Hindborg
