>Organization:
RDTC JSC
>Environment:
System: FreeBSD 9.1-RC1
>Description:
We have got SuperMicro-based server (X8DTU-6+ motherboard),
with CPU having 12 cores (with hyperthreadng that's 24 CPUs).
We downloaded 9.1-RC1 installation CD and tried to boot it.
It panices during igb(4) driver init:
http://www.grosbein.net/img/crash-91rc.png
This is 100% repeatable.
>How-To-Repeat:
See above.
>Fix:
Workaround is to disable MSI-X in /boot/loader.conf:
hw.pci.enable_msix=0
This allows us to boot installation CD and install the system.
I've found this problem is pretty old and should have been fixed
over a year ago in 9.0 but it wasn't.
I've found patch by David G. Lawrence in that thread:
http://lists.freebsd.org/pipermail/freebsd-stable/2011-September/063963.html
The patch needed some corrections to be applied to 9.1-RC1,
so I've corrected it and it solved the problem.
Here is version for 9.1-RC1:
