The issue occured again today. I tried to restart the module

> echo 1 > /sys/module/iwlwifi/devices/0000\:02\:00.0/remove

There is no folder 'devices'

zadesk% ls /sys/module/iwlwifi 
coresize  drivers  holders  initsize  initstate  notes  parameters  refcnt  
sections  srcversion  taint  uevent

> echo 1 > /sys/bus/pci/rescan

Attached the error when trying to rescan.

Thanks,
Bala
