Notes on loading the dump-capture kernel:
|

|

* By default, the ELF headers are stored in ELF64 format to support
|
||||
systems with more than 4GB memory. The --elf32-core-headers option can
|
||||
be used to force the generation of ELF32 headers. This is necessary
|
||||
because GDB currently cannot open vmcore files with ELF64 headers on
|
||||
32-bit systems. ELF32 headers can be used on non-PAE systems (that is,
|
||||
less than 4GB of memory).
|
||||
systems with more than 4GB memory. On i386, kexec automatically checks if
|
||||
the physical RAM size exceeds the 4 GB limit and if not, uses ELF32.
|
||||
So, on non-PAE systems, ELF32 is always used.

* The "irqpoll" boot parameter reduces driver initialization failures

due to shared interrupts in the dump-capture kernel.
