Linux's requirement for swap is=20 unchanged under Xen (ie, if you don't need it native, you don't need it=20 under Xen). In any case, your crashes have nothing to do with swap; you've managed=20 to get an entirely new failure-mode. Looks like it might be something=20 to do with ACPI, but I'm not sure what.
