I just used genkernel for the first time and noticed, after an unpleasant
booting error, that it doesn't include drivers for the LSI Logic (Fusion MPT)
SCSI driver.
Since this is even the default emulation in VMWare, I think it would be a good
thing to include it by default, since you also include every available
SCSI-driver.
I had the same problem as you and tried with the latest version in portage
(3.3.10, but it is soft masked) and it solves the problem.
What you need to do:
echo "sys-kernel/genkernel ~x86" >> /etc/portage/package.keywords
emerge genkernel
Don't forget to remove previous configurations from /etc/kernels before using
genkernel, because the old version saved the configuration with the bug.
Maintainers: Can we have a stable version of genkernel in the tree please?
Either 3.3.10 or 3.3.6 patched.
