6.1 STABLE Strangely Hangs when VLAN enabled.

[ozkan at mersin.edu.tr]

Hi,

I have a HP DL380-G4 server.
Single Xeon 3.0Ghz cpu, two onboard bge NICs and one dual em NIC.

I am using vlan interfaces on bge0 (there is 9 vlan interface on bge0). But systems hangs at a random time without any logs/errors and even panic message! Before system hangs everything works normally. (OS: 6.1 STABLE-200609)
After this problem I tried 6.1 STABLE-200607. Same result!

After removing vlan support from kernel, everything became normal.

I installed same system to another pc (P4-1.4Ghz NICs: rl).
When VLAN enabled, system hangs at a random time again.
I got crazy.

What the problem can be? How can i debug the problem?


Used These Options on That Kernel:

options IPFIREWALL
options IPFIREWALL_VERBOSE
options IPFIREWALL_VERBOSE_LIMIT=100000
options IPFIREWALL_DEFAULT_TO_ACCEPT
options IPDIVERT
options DUMMYNET
options IPSTEALTH
options TCP_DROP_SYNFIN
options NETGRAPH
options LIBALIAS
options NETGRAPH_NAT
options NETGRAPH_IPFW
options NETGRAPH_SOCKET
options NETGRAPH_IFACE
options NETGRAPH_PPP
options NETGRAPH_BPF
options NETGRAPH_VJC
options GEOM_BDE
device  vlan

Have an idea?

Thanks by now.
