callhome:
|
||||
|
||||
Controls the kernel's callhome behavior in case of a kernel panic.
|
||||
|
||||
The s390 hardware allows an operating system to send a notification
|
||||
to a service organization (callhome) in case of an operating system panic.
|
||||
|
||||
When the value in this file is 0 (which is the default behavior)
|
||||
nothing happens in case of a kernel panic. If this value is set to "1"
|
||||
the complete kernel oops message is send to the IBM customer service
|
||||
organization in case the mainframe the Linux operating system is running
|
||||
on has a service contract with IBM.
