From 64670ac8702ec37a00ad6e479f3cacbde0fd4efa Mon Sep 17 00:00:00 2001 From: "Stephen M. Cameron" Date: Tue, 3 May 2011 14:59:51 -0500 Subject: [SCSI] hpsa: do soft reset if hard reset is broken on driver load, if reset_devices is set, and the hard reset attempts fail, try to bring up the controller to the point that a command can be sent, and send it a soft reset command, then after the reset undo whatever driver initialization was done to get it to the point to take a command, and re-do it after the reset. This is to get kdump to work on all the "non-resettable" controllers (except 64xx controllers which can't be reset due to the potentially shared cache module.) Signed-off-by: Stephen M.
