Hi-
Looks like the bootflag code checksum loop is trying to
access across a page boundary.
Alan et al- is there a good trick to get around this?
Alan- should bootflag.o depend on CONFIG_PNPBIOS, and not
just the one line in it that sets the PNPOS flag?
I.e. why execute sbf_* if not CONFIG_PNPBIOS?
I'll generate a patch for this if you like.
Jeff, can you post (or send me) a good boot log (just the
E820 memory mapping part of it will do).
Do you have the ACPI "pmtools"? Getting an ACPI tables dump
would be useful.
