[Bug 1575393] [NEW] Please disable long-obsolete CONFIG_FW_LOADER_USER_HELPER

 

Public bug reported:

The kernel has been able to load firmware by itself for several years
now, and as a result the userspace loading of firmware got dropped in
udev three years ago
(https://github.com/systemd/systemd/commit/be2ea723b1d0).

But Ubuntu's kernels still enable CONFIG_FW_LOADER_USER_HELPER=y. This
will cause 60 second delays, unless we explicitly signal the kernel back
from userspace that we don't use an userspace helper (see
/lib/udev/rules.d/50-firmware.rules). This is a pointless and resource
wasting no-op.

Can we please disable this config option by default? After three years
there's no sign of the userspace stuff ever coming back. It would also
be high time to change the default upstream of course.

Thanks!
