Hi all,
I'm running into crashes with the ixgbe driver on a FreeBSD
8.0-RELEASE system equipped with an Intel X520-SR2 (and using a
Supermicro X8DTU-F motherboard). I was wondering whether somebody
might have seen this before.
I updated the driver to the latest version I found on Intel's
download page, which is 2.0.1. However, the moment I run tcpdump on
my ix1 interface (which is connected to a switch's monitor port), I
see almost immediate crashes of the kind below. Sometimes tcpdump
outputs a few 10s of packets before the system crashes, but most of
the time it doesn't even get that far.
I saw that 8.0-STABLE comes with a more recent version of the
driver. Any chance that that might fix the problem? Any other
thoughts?
Thanks,
Robin
