Bug #: 13193
Summary: Running bz6503.exp results in unresponsive/crashed
machine
Product: systemtap
Version: unspecified
Status: NEW
Severity: normal
Priority: P2
Component: testsuite
AssignedTo: systemtap@sourceware.org
ReportedBy: mjw@redhat.com
Classification: Unclassified
This happens on both "real hardware" with x86_64 f14 (2.6.35.14-96.fc14.x86_64)
and under kvm with x86_64 rhel6 (2.6.32-131.12.1.el6.x86_64).
The following is the result of running make installcheck
RUNTESTFLAGS=bz6503.exp on the rhel6 kvm instance, with echo 9 >
/proc/sysrq-trigger and adding -DDEBUG_SYMBOLS to the testcase:
SysRq : Changing Loglevel
Loglevel set to 9
