big MD_ROOT_SIZE : BTX panic

I buit a kernel, with embedded MFS, MD_ROOT_SIZE was 8 Megs.
Kernel booted and worked fine.

After increasing MD_ROOT_SIZE to 16 Megs, BTX prints
a hexdump and freezes.

A dump looks like this (I've taken first line only)

int=0000000d err=0000e14c efl=0010006 eip=0eff30c4
BTX halted

Any ideas how to fix this ?
