Hi
I'm using Mac OS X 10.3.2 on a PowerBook.  The OS releases the
IOPCCard and IOCardBusDevice from the system during a sleep.  Is this
the expected behaviour?????

This is not the expect behavior. I would try catching the terminate with a breakpoint in your message() method and try looking at the backtrace to see how you got there. Whatever started the terminate may be on a different thread so you have to hunt around for it or set more breakpoints to catch it.

also 10.3.2 seems like a strange release to be testing on? are you only seeing this with 10.3.2 or do you also see this with more current releases like 10.3.9 and 10.4.1?

-rick

The system logs are ; kernel: IOPCCard: shutting down socket 0. kernel: IOPCCard: calling terminate on socket 0 function 0 nub 0xc83000. IOCardBusDevice: releasing socket 0 function 0 from card services.
I've devices connected to the card which gets ejected when the system
sleeps.  I need to prevent this !!!!!!
I get the following 2 messages in my message() function when i 'Power
OFF' the card from menu.
CS_EVENT_EJECTION_REQUEST
CS_EVENT_CARD_REMOVAL
But when the system sleeps i only get the second message and there i
can't do anything more than a clean up work.
Any ideas? Has anyone used a PCCard with devices attached to it like a
cardbus firewire device with harddisks attached?  If yes what is the
behaviour like during a sleep n wake up?
