Subject: [PATCH] aic94xx nexus loss time value
Date: Tue, 7 Mar 2006 16:57:05 -0800 [thread overview]
Message-ID: <20060308005705.GA1516@us.ibm.com> (raw)
The nexus loss time value should not be used for an upper level timeout
value. The nexus loss time is for connection request retries. The usage of
the nexus loss time value + HZ (3 seconds) for sdev->timeout leads to
timeouts under load (Bug 6046).
