Subject: [Bug uprobes/6828] uprobe presence interferes with dd signal handling
Date: Fri, 22 Aug 2008 00:15:00 -0000 [thread overview]

I don't see anything wrong in that module that would explain the problem.
(The module looks fine off hand, though the use of NEWSTATE is superfluous.)
It would help to have report_signal print out what ka and return_ka point to,
along with action. And of course, to have the output you get in the error case.
I tweaked the module to print those, and reproduced the problem on an old F8
kernel (what I have on hand that has old utrace). That version of the code is
no longer maintained except in RHEL5, so this will have to be followed up via
RHEL5 kernel channels.
