[Sachin P. Sant]

While trying to configure kdump with 2.6.24-rc8-mm1 [ on a x86-64 box ]
i ran into this problem. Here is the snippet from dmesg during the
failure. [ dmesg log attached ]

early_ioremap(000000000000040e, 00000002) => -000002103442418
early_iounmap(ffffffff82a0040e, 00000002)
early_ioremap(000000000009dc00, 00001000) => -000002102797312
early_iounmap(ffffffff82a9dc00, 00001000)
crashkernel reservation failed - memory is in use
 [ffffe20000000000-ffffe200001fffff] PMD ->ffff810001200000 on node 0
 [ffffe20000200000-ffffe200003fffff] PMD ->ffff810001600000 on node 0
 [ffffe20000400000-ffffe200005fffff] PMD ->ffff810001a00000 on node 0
 [ffffe20000600000-ffffe200007fffff] PMD ->ffff810001e00000 on node 0

I am using 128M at 32M value for crashkernel parameter.

Thanks
