I have an ALIX 2C2 board.
With CONFIG_NET5501=y, I get a kernel bug, after which the system
doesn't start.
When I unset it, no kernel bug, and it starts fine.
It doesn't matter whether CONFIG_ALIX is set or not.
Of course I don't need CONFIG_NET5501, but it is set in (at least)
Debian kernels, and I think it shouldn't influence other systems.
Linux 4.20-rc5 and 4.19.7 have this problem, 4.18.17 works fine.
See below for info. Do you need anything else?
I barely know C or Git, but I'm happy to test patches or other versions.
I am not subscribed to the list.
Thank you,
Gert
