Not sure what you mean. 2.6.11 has (in drivers/message/fusion/Kconfig)

config FUSION
config FUSION_MAX_SGE
config FUSION_CTL
config FUSION_LAN

2.6.12-rc3 has:

config FUSION
config FUSION_MAX_SGE
config FUSION_CTL
config FUSION_LAN

So I don't think they changed, AFAICS. The config in question has:

CONFIG_FUSION=y
CONFIG_FUSION_MAX_SGE=40
# CONFIG_FUSION_CTL is not set
# CONFIG_SOUND_FUSION is not set

And I'd backed out the rc3 drivers to rc2 (the whole of drivers/message/fusion)
and it doesn't fix it.

I also get several different failure modes, in different trees, one of
which is:
