Re: suspend resume results os freeze

I think you can use a force PCMCIA eject during the power transitions.
Previously, I was not able to detect WLAN card after suspend resume,
while trying to figure out the problem, I tried a miniport drivre
reload by giving a PCMCIA for eject in power down or power up (i guess
so). By that way I was able to reload the driver after resuming. Later
I figured out the problem as a PCMCIA memory timing issue.

Hi,

We are also facing the same issue, when wireless lan module is present
in the pccard socket. Which Wifi module you are using?

You have all the source for the CF WiFi driver? I've experienced
problems with some CF and SD WiFi card drivers that simply never
return from the change power state call to the WiFi driver so the
device actually never enters suspend fully. These where 3:rd party
drivers shipped without source so I ended up with a workaround that
programatically unloaded/ejected the card driver pre-suspend.

Hi Bruce,

The Device works fine, without the card in the socket. Our driver unloads,
when card eject from socket, so this is somehow clear our driver code
resulting os freeze during suspend resume. I am not sure about PM
architecture for NDIS miniport driver. Is the bus driver who changes the card
power state or NDIS miniport driver, during suspend-resume.

Thanks

Hi All,

I am working on a WinCE 5.0  NDIS Miniport driver and it is for CF Wi-Fi
adapter card. When i do a suspend-resume, the OS freezes upon resume. I am
handling NdisDeviceStateD0 power state in my driver code, but i am not
getting why os freezes upon resume.Can you please tell me, how PM works
for
PCMCIA NDIS miniport driver.

Thanks
