Binary package hint: linux-image-2.6.24-18-xen

Description: Ubuntu 8.04
Release: 8.04
linux-image-2.6.24-18-xen:
  Installed: 2.6.24-18.32

Mono applications exit with the following error:
TYPE: 1
**
** ERROR:(mini-amd64.c:192):amd64_patch: assertion failed: (amd64_is_imm32 (disp))

Further investigation indicates that linux-image-2.6.24-18-xen does not obey to the MAP_32BIT flag. Here a relevant portion of the strace of a failing mono app (f-spot):
