There are some differences between the i386 and x86_64 in setting up the probes. The x86_64 need executable regions of memory allocated. Depending on which architecture is being used there could be different failure modes. Is there any other information output? One trick is to just have a regular console, no X so you can see any oops that come up. Are there any entries in /var/log/messages related to this problem? It could be that this experiment is bumping against some limit. You might take a look at the output of the follow to see how many probes and the size of the result .ko: stap -v -p4 -k -e 'probe kernel.function("*") { printf ("%s %s %d %s ", "test-> ", execname(), pid(), probefunc() ) }' It is also possible that some function that should be blacklisted is getting instrumented. You might try to expand tests/testsuite/systemtap.stress/all_kernel_functions.exp to see if you can get a narrow down the boundary between working and crashing. -- What |Removed |Added ---------------------------------------------------------------------------- Summary|Attempting to probe all |Attempting to probe all |kernel functions hangs FC5 |kernel functions hangs FC5 http://sourceware.org/bugzilla/show_bug.cgi?id=2725 ------- You are receiving this mail because: ------- You are the assignee for the bug, or are watching the assignee.
