Description Kris Van Hees 2007-03-18 01:38:08 UTC
Description of problem:

Running the Frysk testsuite triggered the following verbatim kernel messages. 
Mote that this is *not* truncated output.  There really were no additional
messages.  It looks suspiciously like a corrupt kernel oops, especially since
the call trace is empty.

Version-Release number of selected component (if applicable):

kernel 2.6.20-1.2925.fc6

How reproducible:

Somewhat intermittent (mostly a case of usually the testsuite run triggering
some kernel bugs or hang - just not always this one)

Steps to Reproduce:
1. Obtain frysk source tree (CVS HEAD)
2. mkdir build
3. cd build
4. ../frysk/
5. make
6. make check
Actual results:

Kernel messages shown above.

Expected results:

No kernel messages.

Additional info:

Executing the Frysk testsuite on this kernel on i386 has been rather erratic,
with this being one of the possible outcomes.  Sometimes the 'make check'
completes without any kernel errors getting triggered, but I'd say that I have
experienced about 40-50% probability for some kernel problem getting signaled as
result of the testsuite execution.

Comment 1 Roland McGrath 2007-03-22 08:04:42 UTC
Please try 2.6.20-1.2933.fc6 from Fedora updates-testing and tell me if you
still see problems.  That includes fixes for several problems vs 1.2925.fc6; I
do have some further fixes to be included in a forthcoming update beyond what's
in 1.2933, but it is less likely that you will hit those failure modes. 

Comment 2 Kris Van Hees 2007-05-30 17:27:43 UTC
Running with 2.6.20-1.2948.fc6 we no longer see this failure take place.
