[syslinux] SYSLINUX 2.07-pre6 and memdisk decompression problems

[H. Peter Anvin]

Hi there,

I have released SYSLINUX 2.07-pre6 which contains some additional
debugging code in memdisk to try to help track down this problem.

It is unlikely to actually *solve* anything, but perhaps can shed some
light on it.

Please try running it on the failing machines, and report the result as
well as the output of "cksum" on the disk image file.

Thanks,
