Hello, I was wondering if there is any way to recover from FW crash in case of WLAN PCie cards- say we power off card and power on. This would enable hotplug to detect it again and driver's probe routine would do redownload of FW and device is alive again. 1. I went through PCI bus driver sources and came across pci_set_power_state which can be used to set PCI power state to D0-D3hot/D3cold. Suppose we set power state to D3Cold, I dont think dev pointer would be valid again to set to D0. 2. Another idea is something similar to PCI rescan operation via sysfs(echo 1 > /sys/bus/pci/rescan). I am not entirely sure though if this can be applied to single device as this involves scanning all devices on PCI bus. Any help appreciated! Thanks, Avinash
