[Bug 321970] Re: linux-crashdump fails to record crash; reports memory not reserved

[Anders Kaseorg]

Doesn’t work for me on Lucid amd64.  I have 2 GiB of memory, and I have
crashkernel=384M-2G:64M,2G-:128M in /proc/cmdline, but the kernel
detects that I have ever-so-slightly less than 2 GiB of memory, and
therefore gives me a 64 MiB crashkernel:

[    0.000000] Reserving 64MB of memory at 32MB for crashkernel (System
RAM: 2046MB)

When I trigger a panic, it successfully starts the crashkernel, but then
the crashkernel runs out of memory and panics itself.
