Subject: [Bug runtime/3379] New: probe on "atomic_notifier_call_chain" crashes the system
Date: Wed, 18 Oct 2006 07:31:00 -0000 [thread overview]
Message-ID: <20061018073138.3379.guij@cn.ibm.com> (raw)
The command line is:
stap -e 'probe kernel.function("atomic_notifier_call_chain"){}'
If on 2.6.18.1/i686, the screen gets dark and the system is rebooted
immediately;
If on 2.6.18/ppc64, the system is crashed immediately and rebooted.
Several lines of error messages are shown on the console, but not
same every time.
Is there any workaround? or should we add it into the blacklist?
Thanks.
Some examples of error messages on 2.6.18/ppc64:
