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

[Scott Moser]

Public bug reported:

I saw a kernel crash in maverick RC testing.  I will attach console
output here, the system reported is the same AMI, but the issue occurred
on c1.xlarge instance type.

The crash begins like this:
[2725458.312511] invalid opcode: 0000 [#1] SMP ^M
[2725458.312521] last sysfs file: ^M
[2725458.312526] CPU 0 ^M
[2725458.312529] Modules linked in:^M 
[2725458.312536] ^M
[2725458.312541] Pid: 0, comm: swapper Not tainted 2.6.35-22-virtual #33-Ubuntu /^M

[2725458.312565] RSP: e02b:ffffffff81a01ec8  EFLAGS: 00010046^M 

But possibly the interesting piece of data is earlier in the log:
[    0.000000] pcpu-alloc: s91520 r8192 d23168 u122880 alloc=30*4096^M
[    0.000000] pcpu-alloc: [0] 0 [0] 1 [0] 2 [0] 3 [0] 4 [0] 5 [0] 6 [0] 7 ^M

[2725457.617707] Policy zone: Normal^M
[2725457.617711] Kernel command line: root=LABEL=uec-rootfs ro console=hvc0 ^M

There, we go from an uptime of 0.000000 to 2725457 seconds (757 hours)
during boot.
