FW: crash dump on ppc linux

[Xia, Zhao (NSN - CN/Shanghai)]

Hi

Could you help to confirm:
Kexec-tools 2.0.4 + Linux 2.6.33 on MPC8541(PPC32) can work or not?
If not, how to make it? Thanks a lot.

Hi,

I think these questions would be best sent to the
linuxppc-dev at lists.ozlabs.org and kexec at lists.infradead.org lits.

In general I believe that ppc64 is supported by kexec-tools 2.0.3 + 2.6.33.
However, I am not familiar with mpc8541 and there are ongoing improvements
made to ppc64 support for both kexec-tools and the linux kernel.  So if
possible I would try using newer versions - the latest version of
kexec-tools is 2.0.4. And in the case of kexec-tools
the current git branch if the latest release seems to not work.
