Question about failure in PCI power-state change

Hi,

On occasion when I unload and reload driver rtl8192ce, I get the message

"Refused to change power state, currently in D3"

I added additional info to the printk and discovered that it was trying to change to state D0. The problem seems to occur when I have made a connection, unloaded the driver, and reloaded it. If I do not make a connection before unloading, then the problem is a lot less likely.

This is with kernel 3.6-rc4 from wireless-testing. A Google search shows that the problem is usually due to suspend/resume difficulties, but this machine has not been suspended.

I would appreciate any help that you might give in solving this issue.

Thanks,

Larry
