grub error 28

[bunkertor]

hi all

i compiled by myself xen-unstable from hg repo (changeset:   
25835:c70d70d85306)
but i'm facing a problem when i try to boot with xen kernel: Error 28 
Selected item can not fit into memory.
i'm newbie and i cannot understand where i fail...

here's the error (bad...)

[root@xen-02 xen-unstable]# grub

This is pretty large? Any reason its so huge compared to the other ones?

And why not use v3.4 instead of v3.1?

Self built kernel with debug + unstripped modules perhaps? Not sure what
the behaviour of RH's mkinitrd (drakut?) is but if it includes a large
selection of modules, all of which have full debug then it could quickly
add up to those sorts of sizes.

Did you ever successfully run Xen on that system?

Is the very small upper memory value perhaps causing your
problem (i.e. are you dealing with a GrUB issue rather than a
Xen one)? Admittedly I don't know what values GrUB would
display normally, but the E820 map you presented looks
quite unusual, so I wouldn't be surprised if that caused
problems.

first time, hardware is brandnew.

i solved with grub2 (from fedora16), installing last changeset of 
xen-unstable and konrad kernel.
