Probably a dup with bug 1822247.

[Bug 1814237] Re: ubuntu_nbd_smoke_test failed with I/O error on X-4.15
This bug appeared to surface on aws Bionic linux-aws kernel-version": "4.15.0-1035.37", AMD64 We also see this occurring on arm64 instances a1.medium so it does not appear to be arch specific. AMD64 Instances: c5.large , m4.large, m5a.large, r3.large , r5.large, t2.small and t3.medium. This is not 100% reproducible, if affects different instance types during each SRU cycle and appears to be random. However the failure, although not identical bit for bit, is a buffer I/O error I restarted a select few of the failed tests some passed completely and some failed again. I attempted to reproduce on m5a.large. 1.) Deploy m5a.large using cloud prov script with Bionic, ensure kernel is 4.15.0-1035.37 (in proposed at the time of writing this comment) 2.)

Some more useful info: * This issue started to be caught by the testcase after the following test script change: https://kernel.ubuntu.com/git/ubuntu/autotest-client-tests.git/commit/ubuntu_nbd_smoke_test/ubuntu_nbd_smoke_test.sh?id=92ffd0ff14715392730943a898a95920b243ebef * I have traced back these I/O errors on released from a couple of months ago. Checked xenial/linux-hwe and bionic/linux-azure. * This doesn't seem to affect the master kernel, bionic/linux. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1814237 Title: ubuntu_nbd_smoke_test failed with I/O error on X-4.15 To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu-kernel-tests/+bug/1814237/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
