registration error (rc -22)

[Paul Larson]

I've run into a problem using systemtap with recent kernels.  In this 
case, I had a simple probe looking at a kernel module.  It worked fine 
in RHEL5.2 stock kernel.  I updated to 2.6.27-rc6, and also updated to 
the latest git pull of systemtap.  Here's a simple test probe I'm running:
probe module("cxgb3").function("*") {
  print("got here\n")
}

The module used doesn't seem to matter, I've tried several with the same 
result.  Here's the error I get:

ERROR: probe 
module("cxgb3").function("get_regs@drivers/net/cxgb3/cxgb3_main.c:1366") 
registration error (rc -22)

Is this a known problem?  Does it have a known workaround?

Thanks,
Paul Larson
