>Description:
I was following handbook's advice on enabling geom_eli and recompiled the kernel with the following line added to the default config:

device crypto

The resulting kernel seems to skip hardware detection (including HDDs) and then fails as it has no root device. From what I gather from the mailing lists, others have also hit this bug, but it seems to only happen on some platforms, so far I have found posts about it happening on sparc64 and PowerPC.

>How-To-Repeat:
Recompile the kernel on sparc64 or ppc with 'device crypto' added to the configuration, boot the new kernel.
