sorry, the bug got created without me finish all the steps.  

The problem happens with 5.11.7-200.fc33 but also happens on 5.11.7-200.fc32.

1. Enable update-debiginfo in fedora-updates.repo
2. Install kernel-debuginfo.
3. Add the following script in anywhere you like, I put it in /tmp.

# Script to test basic System Tap functionality.

global tickCounter = 0;
global vmallocCounter = 0;

function sayHello()
%{
    printk("systemtap script says hello\n");
%}

probe begin
{
    sayHello();
    printf("hello\n");
}

probe timer.ms(100)
{
    tickCounter++;
}

function sayGoodbye()
%{
    printk("systemtap script says goodbye\n");
%}

// Force use of some basic debug info.
probe kernel.function("vmalloc")
{
    vmallocCounter++;
}

probe end
{
    sayGoodbye();
    printf("counter = %d\nvmalloc = %d\nbye!\n", tickCounter, vmallocCounter);
}

4. run it with following flags:

stap -v -F -o /tmp/a.log -g --disable-cache  /tmp/simpe-test.stp


5. You should see the following error:

FEDORA-2021-c77e63f6bb has been submitted as an update to Fedora 33. https://bodhi.fedoraproject.org/updates/FEDORA-2021-c77e63f6bb

Thanks for the report.  Yeah, when the fedora kernel is rebased, systemtap must backport compatibility fixes.  Would you be able to test the systemtap-4.4-4 build in koji or updates-testing (either f33 and f32)?

FEDORA-2021-6450b3b72d has been submitted as an update to Fedora 32. https://bodhi.fedoraproject.org/updates/FEDORA-2021-6450b3b72d

Yes, I can test that, just let me know when it is ready.

Thanks!

Chung

build rpms are already available here:

https://koji.fedoraproject.org/koji/packageinfo?packageID=615

Thanks.  I will test that package.  Will it get pushed out to the public site soon?

yup, the sooner folks add karma+ to

https://bodhi.fedoraproject.org/updates/FEDORA-2021-6450b3b72d

Just ran my test on f33 and it works.

Thanks for testing!  Would really appreciate karma points to automate moving the builds to the stable yum channels.

Just did for both F33 and F32.
I need that to move also.  
Thanks again for the quick build.

and thank you for the report & quick testing

pleasure doing business with you :-)
