Message #06336
[Bug 2101887] [NEW] ftrace:test.d--filter--event-filter-function.tc from ubuntu_kselftests_ftrace on linux-nvidia-lowlatency is flaky
Public bug reported:
The test case ftrace:test.d--filter--event-filter-function.tc is flaky
for linux-nvidia-lowlatency for noble release. The test fails due to
bursty system behavior and the test selecting the wrong function to
sample: acpi_os_release_object. The sampled function is expected to be
bursty. Increasing the maximum number of retries might fix it.
