generated dnvme.ko makes the /dev disappear on installation

[akshitkanda5]

I compile the source and try the following steps of replacing the exisiting dnvme.ko with the newly generated one:

1. sudo rmmod dnvme
2. sudo make install
3. sudo modprobe

This sequence makes my /dev/dnvme0X00 (X is the bus number) disappear. However when I modprobe the old driver, everything becomes normal. Does this point to an issue with the generated dnvme.ko or am I doing it the wrong way?

Thanks

I have been out of the nvme space for a bit but maybe try to rescan the pcie bus after loading the driver?
Something like: echo "1" > /sys/bus/pci/rescan
