Comment 19 for bug 457767

I'm not convinced that this is a kernel bug. I think that we have not been careful enough to stop Upstart tearing the network interface down and setting it back up again at boot, and that as a result the root filesystem has gone away.

Alt-Sysrq-w just says "SysRq : Show Blocked State".

The target itself seems to work fine; I can log into it from an ordinary system and fiddle about with its filesystem. Furthermore installation onto the target worked fine. I don't think iscsitarget is a likely source of problems here.
