https://bugzilla.novell.com/show_bug.cgi?id=215634 ------- Comment #4 from yxu@novell.com 2006-11-14 05:06 MST ------- I would suggest we skip this test by removing this paragraph: timer 300 fg 1 pthread_spin_lock_1_1 /usr/lib/ltp/runalltests.sh -f /usr/share/qa/ltp/tmp/ltp_temp/openposix.pthread_spin_lock_1_1 wait in the file /usr/share/qa/ltp/tcf/openposix.tcf on that certain machine for a temorary solution. Erik or I will look into the source code and maybe make a patch and apply the patch to ltp and build a new RPM package, but it may take some time, and right now, ltp is in a freezing status. So I come up with the idea of skipping the test that makes the cpu loop. ( Another way could be update your ltp, since the new ltp package is available for sles10. /mounts/work/built/dists/all/sles10-i386/packs-i386/ltp/ltp-20061017/ltp-20061017-1.4.i586.rpm But i am not sure if there is anything new about pthread_spin_lock_1_1 in the new ltp package. ) -- 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, or are watching someone who is.
https://bugzilla.novell.com/show_bug.cgi?id=215634 ------- Comment #5 from pkirsch@novell.com 2006-11-14 06:03 MST ------- There is a similar harder situation in Bug #145160 with testcase sched_yield_1_1. This testcase makes (under special circumstances) machines freeze. So I'm not sure if it is a good idea to skip this testcase. Is there a possibility to ask the author of the testcase of some 'besides effects', if she/he knows one. -- 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, or are watching someone who is.
