From 1901762f2ca2747ed269239ca5332a8023ce4e3d Mon Sep 17 00:00:00 2001 From: Dick Kennedy Date: Fri, 29 Sep 2017 17:34:27 -0700 Subject: [PATCH] scsi: lpfc: fix pci hot plug crash in timer management routines During pci hot plug, the kernel crashes in timer management code. The sli4 remove_one handler is not stoping the timers as it starts to remove the port so that it can be swapped. Fix: Stop the timers early in the handler routine. Note: Fix in SLI-4 only. SLI-3 already stopped the timers properly. Cc: # 4.12+ Signed-off-by: Dick Kennedy Signed-off-by: James Smart Reviewed-by: Johannes Thumshirn Signed-off-by: Martin K.
