RE: [Xen-devel] network hang trigger

[Bin Ren <br260@xxxxxxxxx>]

I can no longer trigger a hang with the latest bkbits. I even use 'ping -f 
-s 6000 dom0' to send hundreds of icmp requests per second, no hang.
The confusing part is that on James' machine, both the big icmp request and 
reply are fragmented. On my machine, no matter how large is the packet, 
icmp request is *NOT* fragmented *without* IP Don't Fragment (DF) flag set! 
And the MTU is 1500.
To make it even more confusing, with normal size (64 bytes in ping dom0), 
DF flag is set!
Could this be a kernel problem? Both of my dom0 and domU are running 2.6.8.1
