[Bug 1354397] Re: Latest fixes from storvsc & scsi drivers for Hyper-V/Azure
Hi Andy,
I see kernel panic on Ubuntu1404 using packages given in http://people.canonical.com/~apw/lp1354397-trusty/ and works fine with the packages available in Ubuntu repository. Hardware is windows Hyper-V. Serial logs are attached.
We didn't see any such issues on Ubuntu 1410 but unable to install
"linux-cloud-
tools-3.16.0-8-generic_3.16.0-8.13~lp1354397v201408121801_amd64.deb" as
its dependency "linux-cloud-tools-3.16.0-8.deb" is missing and we cant
find it over Google. We used earlier version binaries here.
** Attachment added: "Serial logs for Ubuntu1404 kernel crash."
