grub2 issues with rtai kernel patch

[Paolo Rocca]

Hi.

According to my posts on rtai mailing list, grub2 doesn't work with "Low
Latency Desktop" option in kernel recompiling, after rtai-patch applied.
The realtime kernels freeze after grub2 selection: black screen and blinking cursor.
Without rtai patch, kernel recompiling works with Low Latency option.

I've made several tests. If you want, I can send you procedures about.

Thanks
