When I update my system to the latest today(xorg 1.8), I found that mount.hgfs doesn't work again. I get this message from dmesg output:

But.. I can't understand why xorg can impact mount.hgfs. Any idea or hint?
This task depends upon

The kernel was recently updated and compiled with gcc 4.5, external modules might need recompiling. As hgfs is not a kernel module included in the kernel, you should try to recompile it.

I have a same kind of problem with XFS. I can't mount an XFS partition with le lastest kernel version.

The kernel shouldn't have been compiled with gcc 4.5.
