Exactly; and that's why this even gets moved into the upper layer for 2.6.17: http://kernel.org/git/?p=linux/kernel/git/brodo/pcmcia-2.6.git;a=commit;h=66b91eb48d18d4781bddcf8f0ac872e2405903fc > So does that mean the expected behavior from any PCMCIA device in case > of suspend/resume activity is to release its configurations on > suspension and getting new configuration without actually resuming the > task the device was performing at the time of suspension??? Well, most PCMCIA drivers are "dumb" in this regard -- but, for example, the net drivers do stop the queue and restart it on suspend and resume. To do it properly, you do need to stop all activity in the .suspend() callback and continue processing it in or after .resume() Dominik
