fcoe_ctlr_timer_work [libfcoe] crash with kernel Linux version
4.4.155-68-default

Hello Mr. Reinecke,

today morning I get the new distribution of Leap 42.3:

Linux version 4.4.155-68-default (geeko@buildhost) (gcc version 4.8.5 (SUSE
Linux) ) #1 SMP Tue Sep 11 13:07:19 UTC 2018 (4ecc783)

I saw it contains your changes in the scsi environment.

Result of the first test:
