One solution (and with less re-work) is to dump directly in memory, mark pages as reserved, reboot a brand new kernel with an add-on to still have dump pages marked as reserved (without clearing memory, by-passing bios, etc...), and then use the standart disk driver to flush the dump, and then release the pages. I think that main part of the job has already been done with kexec, does someone already looked at it to port on pa-linux ?
