[Bug 2124251] [NEW] noble/plucky: ubuntu ftrace_smoke_test fails on riscv64 due to CONFIG_DYNAMIC_FTRACE, CONFIG_STACK_TRACER, CONFIG_FUNCTION_GRAPH_TRACER, CONFIG_FUNCTION_TRACER not enabled for openstack:risc64vm

  Thread Previous • Date Previous • • Thread Next 
Public bug reported:

ubuntu ftrace-smoke-test has been failing for plucky (6.14.0-9.9.1 ->
6.14.0-32.32) and noble (6.14.0-24.24.1~24.04.1 ->
6.14.0-32.32.1~24.04.1) on openstack:riscv64.vm and testflinger
riscv64.vm servers.
