Manually tested on a P8 node (gulpin) with 5.4.0-89-generic and 5.4.0-90-generic
Conclusion: It looks like a real kernel regression. The following two test cases are failing with 5.4.0-90-generic (passed with 5.4.0-89-generic) [ 736.795192] test_bpf: #142 ALU_MOD_K: 3 % 1 = 0 jited:1 ret 3 != 0 FAIL (1 times) [ 736.795285] test_bpf: #145 ALU64_MOD_K: 3 % 1 = 0 jited:1 ret 3 != 0 FAIL (1 times) Test results: * Kernel: 5.4.0-89 + Source: 5.4.0-89 = PASSED * Kernel: 5.4.0-89 + Source: 5.4.0-90 = PASSED * Kernel: 5.4.0-90 + Source: 5.4.0-90 = FAILED * Kernel: 5.4.0-90 + Source: 5.4.0-89 = FAILED -- 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/1948351 Title: linux ADT test_bpf failure with linux/5.4.0-90.101 Status in linux package in Ubuntu: Incomplete Bug description: This is a scripted bug report about ADT failures while running linux tests for linux/5.4.0-90.101 on focal.
