I figured as quickly as dev is moving I would port to list, if you
prefer bugzilla let me know.
FC4, domU config of nics=3, nics are complied into kernel, stock Xen
options on build.

>I figured as quickly as dev is moving I would port to list, if you >prefer bugzilla let me know.This sounds like bugzilla #183. gnttab_end_foreign_transfer() finds shared[ref].flags is GTF_accept_transfer and happily returns a null frame, which is then happily mapped. When it is dereferenced, you crash. If I change gnttab_end_foreign_transfer to wait for the grant, it never seems to complete properly. I''m still working on>FC4, domU config of nics=3, nics are complied into kernel, stock Xen >options on build.I''m on FC3; nics=2 is enough. It fails on the first packet AFTER the second interface receives its first packet.
