Red Hat Bugzilla – Bug 237560
turn on CONFIG_IPMI_PANIC flags
Last modified: 2012-06-20 12:56:51 EDT
Description of problem (feature request):
When a Linux system panics, there are frequently no clues left after it
reboots. While lkcd and other debug tools are fine for the lab, most
production customers do not want the extra boot time and configuration that
these require. For Linux systems that support IPMI, another option is
available within the OpenIPMI kernel driver module: CONFIG_IPMI_PANIC_EVENT
and CONFIG_IPMI_PANIC_STRING allow the IPMI firmware BMC to save the Linux
panic string in its SEL (NVRAM), which can then be used to
1) know that a panic did occur
2) match this with a known problem/resolution from previous debug
I am proposing that these two CONFIG_PANIC parameters be turned on by default
in the RedHat EL kernels. I don't see that there are any drawbacks to doing
so, and there are clear benefits.
As this is a kernel config parameter i'm reassigning this to the kernel team so
they are aware of this request.
Read ya, Phil
