Problem with MTU > 1500, ifconfig segmentation fault
Hi all,
I am using Xen 2.0.7. I have Broadcom NetXtreme BCM5704 Gigabit Ethernet
(rev 02) cards which support frames greater than 1500.
However when I boot into Xen and try to set the MTU to anything higher
than 1500 (e.g., 4000, 8000 etc) I get a segmentation fault. After this
fault, every command fails with a segmentation fault. I saw a similar
bug report posted here:

allocate_empty_lowmem_region hypervisor function
Hi,
Is there a reason that the allocate_empty_lowmem_region() function in hypervisor.c is only available in Domain 0. It is only included if CONFIG_XEN_PHYSDEV_ACCESS is defined, however, when I remove this it seems to work fine in DomUs.
Thanks,
Ross
