suspend works only once: then "unsupported suspend method"- something about HAL?

[abalone]

All of a sudden Suspend to RAM works only once per boot.

The second time, it either crashes: Screen goes blank, power stays on, I key in SysRq-REISUB because "BUSIER backwards" is the one I can remember...

...or: A somewhat malformatted KDE-plasmatic notification box pops claiming "There was an error while suspending: unsupported suspend method".

Here's what happens when I do it from the CLI:

[~]$ solid-powermanagement suspend to_ram

QStringList Solid::Backends::Hal::HalManager::findDeviceByDeviceInterface(const Solid::DeviceInterface::Type&) error: "org.freedesktop.DBus.Error.ServiceUnknown"

QStringList Solid::Backends::Hal::HalManager::findDeviceByDeviceInterface(const Solid::DeviceInterface::Type&) error: "org.freedesktop.DBus.Error.ServiceUnknown"

QStringList Solid::Backends::Hal::HalManager::findDeviceByDeviceInterface(const Solid::DeviceInterface::Type&) error: "org.freedesktop.DBus.Error.ServiceUnknown"

solid-powermanagement(5894) Solid::Control::ManagerBasePrivate::loadBackend: Backend loaded: "HAL-Power"
solid-powermanagement(5894) HalPower::supportedSuspendMethods: "org.freedesktop.DBus.Error.ServiceUnknown" : "The name org.freedesktop.Hal was not provided by any .service files"
solid-powermanagement(5894) HalPower::supportedSuspendMethods: "org.freedesktop.DBus.Error.ServiceUnknown" : "The name org.freedesktop.Hal was not provided by any .service files"
Unsupported suspend method: to_ram

Means about as much to me as "I'm afraid I can't do that, Dave."

When I kill and reload plasma-desktop, the Sleep and Hibernate options disappear from the Leave menu. To wit,

When I use sudo pm-suspend instead, it crashes when I try to resume.

It was still working last night...

Re: suspend works only once: then "unsupported suspend method"- something about HAL?

Hm. That wacky wireless card might've been the culprit. I removed it. I just hope it's really truly broken and has not turned into a suspend hazard due to issues on the Kubuntu side.
