Subject: [PATCH] kdump: activate udev rules late during boot
|
||
|
|
|
||
|
|
The kdump udev rule is very broad in scope and may slow down
|
||
|
|
booting strongly, especially during the coldplug phase where
|
||
|
|
"add" events for lots of CPU and memory devices have to be
|
||
|
|
processed. Therefore, activate this rule (which has the purpose
|
||
|
|
to support real hotplug rather than coldplug) late in the boot
|
||
|
|
sequence.
