Re: [Mkdump-devel] mini kernel can't load?

[Fernando L. V. C. <fer...@in...>]

Hi Hiromichi,

Thank you for your interest in mkdump!

I will try to reproduce your problem in one of my machines too, but
first I would like to know some more details about the specs of your
machine. Could you please send me the output of the commands below?

# cat /proc/iomem
# cat /proc/cpuinfo
# lspci

Best regards,

Fernando
