From: Luben Tuikov Subject: [PATCH 0/2] [SCSI] Don't overwhelm with messages when a device is unplugged Date: Fri, 3 Nov 2006 01:16:40 -0800 (PST) Message-ID: <665944.84253.qm@web31806.mail.mud.yahoo.com> Reply-To: ltuikov@yahoo.com Mime-Version: 1.0 Content-Type: text/plain; charset=US-ASCII Content-Transfer-Encoding: 7BIT Return-path: Received: from web31806.mail.mud.yahoo.com ([68.142.207.69]:22658 "HELO web31806.mail.mud.yahoo.com") by vger.kernel.org with SMTP id S1752274AbWKCJQl (ORCPT ); Fri, 3 Nov 2006 04:16:41 -0500 Sender: linux-scsi-owner@vger.kernel.org List-Id: linux-scsi@vger.kernel.org To: linux-scsi What follows are two patches. The first I've been carrying for a long time. The second is recent. We see over 2 million messages of sorts when a device(s) is unplugged right in the middle of heavy I/O. "rejecting I/O to device being removed" and "rejecting I/O to dead device"... These are printed so many times that they cause soft-lockup on all 4 CPUs in succession!... The following patches remedy this sad situation. Luben
