Description gmbroome 2013-01-09 01:30:00 UTC

When attempting to load modules before kernel execution, the following error message is given (example module name used):

---(BEGIN LOADER OUTPUT)---

/boot/kernel/if_tap.ko text=0x176 data=0x121+0x212 syms=[0x8+0xed+0x8+0xa2d]
loading required module ''
can't find ''

---(END LOADER OUTPUT)---

The requested module fails to load, and shown by lsmod (in loader) and kldstat (post-boot), and the functionality is not available in the booted system.

The problems occurs regardless of whether or not a proper linker.hints is present; loader behavior does not change either way.

All tested modules are affected.  Each modules loads and functions normally post-boot.

Fix: 

No fix known at this time; attempted stock 9.1R loader / kernel / modules, as well as custom-built variants.  All produce the same error.
How-To-Repeat: System:
  Power Mac G5 dual-CPU
  4GB RAM
  FreeBSD 9.1 installed to local HDD, using standard APM maps and UFS partitions.

Attempt to load a module at boot.  The load fails.

Hi,

you should be able to load modules with a 9.1-STABLE tree.

I committed a fix for this with r240249. You might also want r240782
which resolves module dependency resolution.

Syncing the loader source and rebuilding the loader should be suffcient.
