On a lot of devices, the "power button" is the resume button. When you "turn it off" it suspends, and when you "turn it on" it resumes. > Also if you didn't eject the socket, at resume the device will be > powered up again, my patch just prevents that a pre-powered off device > to be turned on at resume time. > > However you should consider that some embedded systems have fixed > PCMCIA devices that can't be removed so there are no reasons to detect > them after resume, nobody can change them. :) > > Also battery powered devices can go very frequently to sleep and the > current behavior force the user to switch off the unused device each > time the system resumes from sleep. I realise that. I do work on embedded devices, and this behaviour is explicitly there to support embedded devices. I've suggested a workable solution to you which allows both of us to have the behaviour we both desire from the system. That sounds like a negotiated solution to me... -- Russell King Linux kernel 2.6 ARM Linux - http://www.arm.linux.org.uk/ maintainer of: - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
