kuzzle and scobee are actually failing with 64k generic and 64k lowlatency.
The only ARM64 box that can pass with 64k is ARM64 node starmie-kernel. Others like dazzle, kuzzle, helo-kernel, kopter-kernel, scobee-kernel are all failing with 64k. I wonder why we're having this difference. -- 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/2000778 Title: pmtu.sh in net from ubunut_kernel_selftests crash SUT with K-5.19 Status in ubuntu-kernel-tests: New Status in linux package in Ubuntu: Incomplete Status in linux source package in Kinetic: Incomplete Bug description: Issue found with Kinetic 5.19.0-27.28 and 5.19.0-28.29 in this cycle (20221114) on these SUTs * P9 baltar * ARM64 kuzzle * ARM64 howzit-kernel This should not be considered as a regression as the net test cannot be built in 5.19.0-24.25 Test log: ubuntu@baltar:~/autotest/client/tmp/ubuntu_kernel_selftests/src/linux/tools/testing/selftests/net$ sudo ./pmtu.sh TEST: ipv4: PMTU exceptions [ OK ] TEST: ipv4: PMTU exceptions - nexthop objects [ OK ] TEST: ipv6: PMTU exceptions [ OK ] TEST: ipv6: PMTU exceptions - nexthop objects [ OK ] TEST: ICMPv4 with DSCP and ECN: PMTU exceptions [ OK ] TEST: ICMPv4 with DSCP and ECN: PMTU exceptions - nexthop objects [ OK ] 'socat' command not found;
