I would just like to add that on all versions of ubuntu after 12.04 the version of brocade drivers that are included with the kernel is problematic and will result in rx queue kernel panics under high network and CPU load.
The issue has been resolved by the inclusion off 3.2.5.1 drivers in the 4.2+ linux kernels.
4.1 has the new driver and firmwares, but is broken and will not initiate the cards at boot time:
So, if you are experiencing the bna rx kernel panic stacktrace you can try updating to the newest kernel and firmwares as outlined below:
-----------------
The kernel files for can be installed for 64 bit systems as follows:
To get the firmwares:
(as root):
To install 4.2.0 kernel (ubuntu team hasn't posted 4.2.1 yet - which is the current stable, although marked unstable I have been using it for a while without any stability issues - much less crashing than with the old 3.2.3.0 drivers/3.x combo)
(as root):
Once done, reboot and things should come up as normal.
A quick check should reveal that you are now running the newest firmware and drivers:
(as root):
If something doesn't work or you wish to revert - you can go back by removing the 4.2.0 kernel packages (grub should rebuild after)
(as root):
As a note, if your dpkg or apt script complains that the disk is full - you have to remove some older kernels taking up space in /boot (often its own partition of very small size) before you can install/remove any kernels. You probably have some kernels for 3.13, 3.16 or 3.19 in /boot that are no longer being used and could be moved/deleted.
Now you can reboot and the old kernel will show up with the old drivers.

If something doesn't work or you wish to revert - you can go back by removing the 4.2.0 kernel packages (grub should rebuild after)
(as root):
Code:
apt-get remove 'linux-headers-4.2.0*' 'linux-image-4.2.0*'
update-initramfs -uk all
update-grubNow you can reboot and the old kernel will show up with the old drivers.
