Install xfstests per http://en.opensuse.org/SDB:XFStests 2. Reboot into a nice clean environment 3. Login to a text console 4. Set the environment variables as described in the wiki 5. run "./check 255" without first mounting the test partitions. (test 255 is attached) Actual Results: It seems to vary by which kernel I test exactly what happens, but I always get an oops. With the 2.6.39.2-36-default from Tumbleweed, I was able to interact with the system for a short while, but after cntrl-alt-F7 the system locked up and I had to hard boot. Expected Results: Test 255 is not yet a trusted test, so I don't know exactly what should have happened, but not a oops. There are at least 4 ways to run test 255. All seem problematic, but I haven't tested much since a reboot is required between tests. 1) With test partitions not mounted "./check 255" 2) With test partitions not mounted "./255" 3) With test partitions mounted "./check 255" 4) With test partitions mounted "./255" Again, test 255 is NOT finished, but it should not be causing oops messages. I have NOT tested the 3.0 kernel. This same test works to some extent on another machine. (Possibly 32-bit, I haven't chased it down.) I have no idea what it is in test 255 that causes the oops. -- Configure bugmail: https://bugzilla.novell.com/userprefs.cgi?tab=email ------- You are receiving this mail because: ------- You are on the CC list for the bug.
