Subject : [KERNEL 2.6.26-rc4] bugreport : pata_pcmcia with Sandisk Extreme III 8GB Submitter : Komuro <komurojun-mbn@nifty.com> Date : 2008-06-07 13:37 References : http://marc.info/?l=linux-kernel&m=121284627119861&w=4 Handled-By : Tejun Heo <htejun@gmail.com> Handled-By : Dominik Brodowski <linux@dominikbrodowski.net> This entry is being used for tracking a regression from 2.6.25. Please don't close it until the problem is fixed in the mainline.
Caused by: commit f046519fc85a8fdf6a058b4ac9d897cdee6f3e52 Author: Tejun Heo <htejun@gmail.com> Date: Mon May 19 01:15:08 2008 +0900 libata: kill hotplug related race condition
Hmm, I get deadlock, not any messages, and I need plug/unplug/plug for the error to fully manifest itself. Seems like different problem?
Before the "kill hotplug related race condition" patch, only 0.0 exist at /sys/bus/pcmcia/devices. but after this patch, 0.0 and 0.1 exist at /sys/bus/pcmcia/devices. This 0.1 causes the problem...
I'm seriously running out of ideas for this one. I can't really see how the race condition fix patch can bring the second pcmcia port into life. Strange. :-(

Fixed Its a pcmcia core bug - changing the objects hide it because pcmcia was reading wrong data via dev->private_data. Patch posted to Linus/LKML
