Subject: qla2xxx UBSAN warning in 4.14-rc1
Date: Mon, 18 Sep 2017 13:49:47 +0300 (EEST) [thread overview]
Message-ID: <alpine.LRH.2.21.1709181335450.628@math.ut.ee> (raw)
Hello, I decided to widen the coverage of my kernel testbed and put some
FC cards into servers. This one is a PCI-X QLA2340 in HP Proliant DL 380
G4 (first 64-bit generation of Proliants). I got a UBSAN warning from
qla2xxx before probing for the firmware.
This is reproducible with or without firmware being available.
[ 3.905570] qla2xxx [0000:00:00.0]-0005: : QLogic Fibre Channel HBA Driver: 10.00.00.01-k.
[ 3.905977] qla2xxx 0000:06:02.0: PCI IRQ 78 -> rerouted to legacy IRQ 18
[ 3.906172] qla2xxx [0000:06:02.0]-001d: : Found an ISP2312 irq 18 iobase 0xffffc90000139000.
