Netmap seems to randomly cause Kernel panic on shutdown

[Steven Crangle]

Hi,


I'm looking for a bit of help to track down the reason behind this kernel panic, it seems like netmap works fine for the majority of the time, but occasionally it will cause the box to kernel panic.


The machine is running FreeBSD Current from a few weeks ago (Rev 296937)


And it has a Chelsio T520-SO network card in it.


We've been developing with netmap for a while now, and while the kernel panic doesn't seem to be 100% reproducible, it's happening regularly enough to cause alarm!


Thanks for any help!


Steven
