Hi,

new with kernel 4.2 (perhaps 4.1 also), the error repeats every 120seconds:

I used kernel 4.0.6 up to now, no problems there.

dmesg
Comment 2 Daniel Mayer 2015-09-08 07:43:53 UTC
dmesg shows:

[   12.394101] bfa 0000:0b:00.0: Running firmware version is incompatible with the driver version
[   12.593368] bfa 0000:0b:00.0: bfa init failed

So most likely the kernel firmware need an update.
Comment 3 Daniel Mayer 2015-09-08 07:46:12 UTC
Because not in dmesg visible:
The Brocade runs the firmware 3.2.5.0

Sorry for the many messages. I can't find an "edit" button...
Comment 4 Daniel Mayer 2015-09-19 15:38:07 UTC
I updated the firmware to 3.2.5.1, as they find themselves in the lib/firmware.
Same error. Same error with 4.3-rc1, too:

"[   12.862681] bfa 0000:0b:00.0: Running firmware version is incompatible with the driver version
[   13.065387] bfa 0000:0b:00.0: bfa init failed
[   13.069794] bfa 0000:0b:00.1: Running firmware version is incompatible with the driver version
[   13.268674] bfa 0000:0b:00.1: bfa init failed
"
Comment 5 Daniel Mayer 2015-09-21 13:41:16 UTC
Update by myself:
I found in drivers/scsi/bfa in the file bfad.c at lines 66-69 the entries:

#define BFAD_FW_FILE_CB         "cbfw-3.2.3.0.bin"
#define BFAD_FW_FILE_CT         "ctfw-3.2.3.0.bin"
#define BFAD_FW_FILE_CT2        "ct2fw-3.2.3.0.bin"

and changed them to *3.2.5.1.bin. The files are present under Ubuntu 15.04x64 Server in /lib/firmware.

The error messages have disappeard. Surely nothing like a patch but more an individual solution, but it works and clarifies:
Please update the bfa-driver to fetch the correct firmware-files according to the firmware on the card.

Qlogic mostly shows 3.2.5.0-firmware on their site, but only under "RedHat x64" shows the 3.2.5.1-liveCD. So there may be the need of a man-entry or FAQ or st like that.
