Syslinux - Jul 2013 - memtest86 does not work after upgrading to PXELINUX 6.01

Dear Colleagues,

memtest86 does not work any more after upgrading PXELINUX to 6.01.
When trying to boot, I get the following message:

PXELINUX 6.01 2013-07-04 Copyright (C) 1994-2013 H. Peter Anvin et al
Loading memtest86... ok
Booting kernel failed: invalid argument
boot:

The config is simple:

DEFAULT memtest

label memtest
 kernel memtest86


Any ideas? What additional information can I provide?
That is "Memtest-86 v4.3" if it's important.

What was the previous version of Syslinux you used? Presumably 4.xx?
This is a known bug in the 5.xx and 6.xx releases. A fix is being worked
on.

Yes.

Well, it's odd, PXELINUX 6.01 + memtest86 still works on VirtualBOX,
but not on any "real" NICs I have tried.

For the present I had to use a workaround (memdisk + memtest86 floppy
image work all right).

Are you able to try 6.02-pre12? There's been at least one successful
report when booting memtest with that version.
