contigmalloc1 panic on install

[Ryan Carmichael]

I've recently tried to install both 5.1 Release and 4.8 Release on a Toshiba
laptop and I get this error:

panic: contigmalloc1: size must not be 0

during boot up (see full boot text below).  4.8 will actually install fully
before giving this error, but 5.1 won't even get that far.  From doing some
reading it seems to be an ACPI error but with 5.1 the option to "boot with
ACPI disabled" gives the same result. Possibly it is an AGP error since that
is the last line before the panic (see below).

I'd appreciate any pointers, though buying a new laptop may be in order :)

Please reply to my e-mail address as I am not on this list.

Thanks,
Ryan Carmichael
