[Bug 1350522] Re: EC2 kernel crash due to vmalloc
* It would be useful to correlate Xen hypervisor versions. On each launch with warnings we need to grep 'Xen version' in dmesg.
Xen 4.2, w/ Amazon patches.
* Can you add the following to kernel cmdline options to get additional debug information:
initcall_debug debug ignore_loglevel LOGLEVEL=8
Added in the latest set of logs
* If you see this problem in an instance, if you reboot does the same problem occur?
Multiple reboots yields the same issue, but at different points
