[OpenAFS-devel] OpenAFS on ia64_linux24

[Buhrmaster, Gary]

Alf,

Using a google search, it appears that if the
kernel is recompiled with CONFIG_MODVERSIONS
it will work (due to a bug in the RH
kernel regarding the GPL restrictions).

I would guess that SGI (re)compiled the
RHAS kernel without module versioning.
(But that would only be if you believe
everything you read on the web :-)
