A question about PCI suspend-resume functionallity

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



Hi,


We are testing Intel Gigabit adapter driver (igb) under Fedora 20, kernel 3.14.4 for the following use-case:

(*) Adapter is connected to the PCIE slot
(*) We put the system under suspend by running pm-suspend from user-space
(*) Remove the adapter from the PCIE slot
(*) Wake up the system

Currenlty, we got kernel panics and the system got stuck.

My question is - does the PCI subsystem logic calls the driver remove function when driver resume function returns with error code?

Or should I implement the call to igb_remove from igb_resume in the Intel driver?

Thanks,
Igor Bezukh
