Subject2.6.30: hald crashes on resume from STR apparently on LED device
Date
I did not experience this crash under 2.6.29. I got it under 2.6.30 
(both rc and final) with varying frequency. At least for me it is 2.6.30
regression.

hald aborts on D-Bus assertion with stack trace below.Program received
signal SIGABRT, Aborted.

Appearance of hald-addon-leds may be red herring; still here is the only
led device I have (for Intel 3946ABG).

udi = '/org/freedesktop/Hal/devices/leds_iwl_phy0_radio'
info.addons.singleton = {'hald-addon-leds'} (string list)
info.capabilities = {'leds'} (string list)
info.category = 'leds' (string)
info.interfaces = {'org.freedesktop.Hal.Device.Leds'} (string list)
info.parent = '/org/freedesktop/Hal/devices/pci_8086_4222' (string)
info.subsystem = 'leds' (string)
info.udi = '/org/freedesktop/Hal/devices/leds_iwl_phy0_radio'
(string)
leds.device_name = 'iwl-phy0' (string)
leds.function = 'radio' (string)
linux.hotplug_type = 2 (0x2) (int)
linux.subsystem = 'leds' (string)
linux.sysfs_path =
'/sys/devices/pci0000:00/0000:00:1c.1/0000:0c:00.0/leds/iwl-phy0::radio'
(string)


This is Dell XPS M1330 notebook. I am ready to provide any required
information; so far crash is reproducible after several suspend/resume
cycles.
