I'm using X230i with Windows 8.
The Ricoh driver (risdxc64.sys) is using 25% CPU most of the time (0% after restart, but 25% after some time)
I uninstall the driver, and the CPU time was solved.
However, I could not use the card reader once I uninstall it
Is there other driver available without causing this 25% issue?
It's really a big threat to the battery life

You can use the "old" Windows 7 driver which works fine under Windows 8.
Have you tried the newest driver for Windows 8? Since I installed it, I haven't had any CPU spikes caused by this driver . Try it!

there is a similar topic here:
but there is no solution as well...

Yeah, the problem also reappeared with my system (using newest Windows 8 drivers).
The problem is that most people won't really notice the problem, because it "only" degrades battery life but not the perceptible speed of the system. I hope lenovo/ricoh is working on a solution for this problem.

I just performed a clean install of Windows 8 Pro with Media Center onto my X220 and installed the Ricoh PCIe SDXC/MMC Host Controller driver (date: 9/21/2012, version: 188.8.131.52, filename: risdxc64.sys) and have not yet experienced a problem. CPU utilization hovers around 1-2%.
All I have done so far is install Windows 8 Pro, perform Windows Updates, install the ThinkVantage System Update package, let it update, and then purchase a Media Center key.
In the 4-in-1 card slot is a Patriot Memory EP Series 64GB SDXC Card.
Is there something I specifically need to do to reproduce the problem?

I don't use hibernation or sleep on any of my computers, so that may be why I have not been able to reproduce this.

I have an X230 and am running Windows 8.1 x64, for which a distinct driver package is available - version 2.25.18.01. It still does not address this issue.
I acquired this laptop only recently. Until then, I was using an X220 which had exactly the same problem with version 2.22.18.01 of the driver package.
Before that, I ran Windows 8 - then Windows 8.1 - on an X201. Paradoxically, that was the last ThinkPad model where I had a glitch-free exerience.
The only viable workaround is to either reboot on each occasion that the symptom arises or to disable the card reader outright. That this issue has dragged on for so long, between multiple driver versions and consecutive Thinkpad models, is preposterous.
I would urge Lenovo to get their act together and work with Ricoh to address this bug, once and for all. They should also extend their customers the courtesy of providing updated versions of all previously defective drivers, not just those that concern the model du jour.
