Hi, I have just configured a Linux box with kernel 2.6.16.7 and configured two ethernet interfaces (with MTU 1500) in bridge mode. CONFIG_BRIDGE_NETFILTER is enabled. The problem is that ping -s 1500 192.168.0.2 doesn't work from 192.168.0.1 if the systems are separated by the bridge. Normal ping with smaller packet size works ok. What is wrong?

Looks like the GSO is involved? I got this while running Dom0 only (no guests), with a BOINC/Rosetta@home application running on all 4 cores. changeset: 10649:8e55c5c11475 Build: x86_32p (pae). ------------[ cut here ]------------ kernel BUG at net/core/dev.c:1133! invalid opcode: 0000 [#1] SMP CPU: 0 EIP: 0061:[<c04dceb0>] Not tainted VLI EFLAGS: 00210297 (2.6.16.13-xen

Hi, I have 2 servers which are connected to a gateway machine. The gateway and one server are running Linux 2.6.16.2, while the third machine is running 2.6.16.5. The two ethernet ports on the gateway which are connected to the servers are combined into a single ethernet bridge device. Ever since 2.6.16, I have noticed that I can no longer cross-mount the two servers' /home directories via
