Created attachment 187061 [details] dmesg
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.
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...
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 "
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.
