Avoid this.
Even if you don't avoid it, before you attempt to re-install a kernel you rolled, read the manpages on the following:
and check out the content of /proc/filesystems (to see what filesystems you're supporting in your current kernel).
To see what's in your current kernel, look at your config file, which lives in /boot. It'll be /boot/config-`uname -r`.
And again, I urge you not to recompile. Maybe you know more about this stuff than I do (which is likely), but you want to know a lot more than I do before you do it.
Which is weird, because all my other kernel rerollings and installations in debian -- on desktop systems without other OS partitions -- have gone really smoothly.
Whatever. Let the buyer beware, and know what you're getting into.
But more power to you.
