            Bug ID: 28394
           Summary: Systemtap 4.6 on Centos 8.4/4.18 kernel died in
                    nfsd-trace example
           Product: systemtap
           Version: unspecified
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: runtime
          Assignee: systemtap at sourceware dot org
          Reporter: bill at broadley dot org
  Target Milestone: ---

I tried the Systemtap on Rocky-8.4 (a recompile of RHEL-8.4) *AND* with the
current git branch and tried the nfsd-trace example.

Kernel/Env:

[root@nas-1-0 systemtap]# uname -a
Linux nas-1-0 4.18.0-305.19.1.el8_4.x86_64 #1 SMP Wed Sep 15 19:12:32 UTC 2021

[root@nas-1-0 systemtap]# stap-prep 
Configuring for kernel release 4.18.0-305.19.1.el8_4.x86_64
[root@nas-1-0 systemtap]#

Rocky-8.4/RHEL-8.4 provided systemtap:

[root@nas-1-0 systemtap]# /usr/bin/stap --version
Systemtap translator/driver (version 4.4/0.182, rpm 4.4-11.el8_4.0.1)
With the Rocky-8.4/RHEL-8.4 provided stap:
