Maybe new driver tries to use > some feature that is missing (or broken) in the old firmware? A little bit of context: I'm maintaining the kernel package for a Qubes OS distribution. While I can try to update firmware on my test system, I have no influence on what hardware users will use this kernel, and which firmware version they will use (and whether all the vendors provide newer firmware at all). I cannot ship a kernel that is known to break network on some devices. > > Also, you mentioned that on another system this issue doesn't reproduce= , do > > they have the same firmware version? >=20 > The other one has also 1.1-4 firmware.
