Freeing fadump memory can take a long time and doing it when we are going to
|
|
|
|
|
reboot anyway is pointless.
|
|
|
|
|
|
|
|
|
|
In bsc#1034169 a kernel oops is triggered by freeing fadump memory killing
|
|
|
|
|
save_dump.sh and preventing the reboot requested by the user from happening
|
|
|
|
|
entirely.
|
|
|
|
|
|
|
|
|
|
Avoid the issue and speed up reboot by not freeing fadump memory when reboot is
|
|
|
|
|
requested.
