Thomas, All,

On 2014-02-07 09:20 +0100, Thomas De Schampheleire spake thusly:
> When mdev /dev management is chosen in the buildroot configuration, the
> Linux configuration is updated automatically to set option
> CONFIG_UEVENT_HELPER_PATH to "/sbin/mdev". However, the help text of this
> option explicitly recommends not setting this option due to large
> performance impact during boot (experienced first hand by the reporter ánd
> author).
> 
> The mdev startup script S10mdev already sets the helper during userspace
> boot, which will make sure mdev is working correctly.
> 
> Fixes bug #6596: https://bugs.busybox.net/show_bug.cgi?id=6596
