Subject: storvsc loops with No Sense messages
Date: Tue, 29 Jan 2013 16:28:01 +0100 [thread overview]
Message-ID: <20130129152801.GA671@aepfle.de> (raw)
KY,
while attempting to install the upcoming openSuSE 12.3 in a hyper-v
guest (1 vcpu, 512MB) hosted on Windows Server 2012 I see a hanging
guest after formating the root partition, when the installer starts to
write files to it. After booting the install kernel with
'ignore_loglevel' I see a flood of the "No Sense" messages shown below.
I can reproduce it every time with 12.3.
The sglist init patch does not fix it for me.
Hannes did many storage related backports for SLES11 SP3, and sometimes
the installer hangs at similar points during a fresh SP3 install.
The same procedure works fine on Windows Server 2008.
Any ideas what 2012 does differently? It happens with a plain 3.7.n
kernel. I will try 3.8-rc now, and see if it happens as well.
Olaf
