Hi!

I got test failure when I submitted -rt branch for testing.

https://gitlab.com/cip-project/cip-kernel/linux-cip/-/pipelines/197703780

This seems to be "real" failure:

With no network, it is easy to understand that tests would fail.

x86_siemens, OTOH, seems to be infrastructure error
(bootloader-interrupt timed out after 599 seconds).

Let me investigate it some more.

Best regards,

I re-ran the test with same sources, and failure is still there.

I tried rt+v4.19.147-cip35 -- e8bcfc1349886ef3cf6625a0bc9cd25ddf80112c
-- fails, too.

Let me try commit 1d9c4c7e291d5f49ab07402ef739f98fac6e7adb (tag:
v4.19.144-cip34). ... that one works.

To be sure, let's try older rt commit:
f15040b9d853b9cfbcdd4707d9be2593b42b000b ( v4.19.142-cip33-rt14 /
-rt63). That one works ok.

-rt63-rebase and -rt64-rebase trees have same commits on top.. in
fact, they seem to have same commits. That probably means nothing
changed in -rt. But it looks like there's commit in -stable, touching
relevant area.

    ravb: Fixed to be able to unload modules

Let me investigate some more.

This one went away when I resubmitted same kernel... so lets ignore it.

[cip-dev] Pending problem in v4.19.148 -- arm64/renesas test failing for v4.19.148-cip35-rt15 (-rt64)

And this one seems to be responsible. I believe -cip will need to do
something with it when it tries to merge 4.19.148... I hit it early
because 4.19.147-rt is not available, so I merged 4.19.148-rt with
4.19.147-cip.

Fix can be as simple as reverting
fb3a780e7a76cf8efb055f8322ec039923cee41f... I'm pretty sure noone
unloads modules in production.

Best regards,
