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:

Could be doable, but I don't see a particular benefit. Having a single
error loop is an advantage by itself.
The coding style is a suggestion. Note the difference between

ext2resize for Ext3
Hi.
What is the state of ext2resize for Ext3?
How about the online-ext3-patch?
