Oh, I see.  This bug is not corrected in 2.6.18.5.
As a side note, in contrast, in  "arch/x86_64/kernel/"  there are
seemingly no files having anything to do with efi.  Maybe this is of no
importance though.

:-)

I sincerely apologise for the long attachment in advance; here I send
you the dmesg output in full, most of it I do not understand.
