[Bug 1959610] Re: ubuntu_kernel_selftests / ftrace:ftracetest do_softirq failure on Jammy realtime
This bug is awaiting verification that the linux- oracle-5.15/5.15.0-1006.8~20.04.1 kernel in -proposed solves the problem. Please test the kernel and update this bug with the results. If the problem is solved, change the tag 'verification-needed-focal' to 'verification-done-focal'. If the problem still exists, change the tag 'verification-needed-focal' to 'verification-failed-focal'. If verification is not done by 5 working days from today, this fix will be dropped from the source code, and this bug will be closed. See https://wiki.ubuntu.com/Testing/EnableProposed for documentation how to enable and use -proposed.

[Bug 1959610] Re: ubuntu_kernel_selftests / ftrace:ftracetest do_softirq failure on Jammy realtime
** Description changed:
- do_softirq does not exist on preempt RT kernel.
+ [Impact]
- This is causing a failure in ftrace:ftracetest which reports: "echo: I/O
- error".
+ * ubuntu_kernel_selftests / ftrace:ftracetest fails on realtime kernel.
+
+ * ftrace:ftracetest which reports: "echo: I/O error". This is caused by
+ using "do_softirq" in test which does not exist on preempt RT kernel.
+
+ [Fix]
+
+ * Use other function.
+ * Upstream commit 6fec1ab67f8d ("selftests/ftrace: Do not trace do_softirq
because of PREEMPT_RT")
+
+ [Test Plan]
+
+ * Run the test on regular (base) and realtime kernel.
+
+ [Where problems could occur]
+
+ * Only ftracetest tests.
+
+ [Other info]
Failure is reported for step 32 in Jenkins job:
