[Bug 1189808] New: udp datagrams received out-of-order with kernel 5.3.18-lp152.72.1 onwards

http://bugzilla.opensuse.org/show_bug.cgi?id=1189808 Bug ID: 1189808 Summary: udp datagrams received out-of-order with kernel 5.3.18-lp152.72.1 onwards Classification: openSUSE Product: openSUSE Distribution Version: Leap 15.2 Hardware: x86-64 OS: openSUSE Leap 15.2 Status: NEW Severity: Normal Priority: P5 - None Component: Kernel Assignee: kernel-bugs(a)opensuse.org Reporter: simonalogan(a)gmail.com QA Contact: qa-bugs(a)suse.de Found By: --- Blocker: --- User-Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/92.0.4515.159 Safari/537.36 Build Identifier: Hi folks, We have observed that Leap 15.2 kernels 5.3.18-lp152.72.1 onwards frequently deliver UDP packets out of order. The issue is 100% reproducable on Haswell hardware, for example an Intel(R) Core(TM) i3-4130 CPU @ 3.40GHz machine. I know UDP makes no guarantee of packet delivery order, but previous kernels always seemed to deliver packets in order. Did something change in 72.1 that would affect this? We noticed this affecting video streaming, but it is easily reproducable using iperf. Please see steps below. Thanks, Simon Reproducible: Always Steps to Reproduce: - Run an iperf server on the Haswell box. iperf3 -s - Now run a set of 10 tests, asking a remote client to receive 300Mbit blocks of UDP data. for iter in 0 1 2 3 4 5 6 7 8 9; do echo "iter: $iter"; iperf3 -c 192.168.1.10 -u -b 300M -R | grep "datagrams received out-of-order"; done Using kernel 5.3.18-lp152.60 I see no out-of-order datagrams. Using kernel 5.3.18-lp152.87 I see > 10k out-of-order datagrams on each run.

The GPU hang is relatively hard to hit, as it usually takes 5 to 7 days before it crashes. After a hang it attempts to reset the GPU, but sometimes the reset fails and system stays sort of unresponsive. You can still access it over network, and there's some sort of reaction on keyboard events, but display stays dead. Also, it seems to bring PCIe bus down to 1.0 mode, and it stays that until reboot. There's an upstream bug open that may have something to do about it: https://gitlab.freedesktop.org/drm/amd/-/issues/716 That particular GPU works fine on Windows machine openSUSE Leap 15.2, kernel 5.3.18-lp152.57-default #1 SMP Fri Dec 4 07:27:58 UTC 2020 (7be5551) -- You are receiving this mail because: You are the assignee for the bug.
