hibernate

my laptop:
cpu Core2 T6500
mm 2G
hdd SSD 64G(sda1-/ sda2--swap)
wlan0 intel wifi link 5100agn
eth0 Broadcom BCM5784M Gigabit

usually the boot time is 20+ sec,from click the powerkey,to the gnome2 desktop.
today I experience hibernate.in kernel config ACPI,select hibernate support and use /dev/sda2 as resume partition.

when hibrenate,it's about 20+ secs,10sec more than shutdown.

but when power on and resume from hibernate,it's too long,it wait at one step for about 1 minute.then print ""iwlwifi 0000:06:00.0:request for firmware file 'iwlwifi-5000-5.ucode' failed."
after normal boot or resume from hibernate,wlan0 is able to work

the file iwlwifi-5000-5.ucode exists in /lib/firmware/.
I have select related configs in kernel,and emerge iwlwifi-5000-ucode package.
when normal boot without hibernate,this fail info doesn't exist.
some webpage say /etc/hotplug/firmware.conf define the path of firmware.but I don't have this file in /etc/hotplug.

how to solve thank you

It is possible that the driver requests the firmware file when the root filesystem is temporarily unavailable during suspend/resume.

Try the following in your kernel config, this will compile the firmware into the kernel image:
