[Bug 651370] Re: ec2 kernel crash invalid opcode 0000 [#1]

[Mikael Gueck]

Brandon's and Scott's workaround works for me partly, but the kernel on
an instance started in such a way seems to detect only 32 GB of memory
even for a m2.4xlarge instance which should have 68.4 GB available,
according to the EC2 instances page. Is this a side-effect of the
workaround, or a completely separate bug?

Maveric results:
