[syslinux] Sysylinux-6.03 freezes at Loading kernel..., works smooth with 4.06 via SD-CARD

[Michael Kasprowicz]

Hi
I have tried to install syslinux 4.06 on the SD card again, it works like a
charm.

I am being very carefull with c32 files from the same version bootloader.
No success.

I am also unmounting /dev/sdb1 before installing syslinux, as mentioned in
the given documentations.
In the pasted syslinux.cfg content--- I have also tried using only one
DEFAULT directive. No success.
syslinux boots successfully into SD-CARD thats for sure, as I do get the
boot prompt and I can even choose to load initrd0.img first, which shows
loading successful. But when it comes to loading the kernel, the system
hangs.

UEFI mode is disabled in my BIOS.
Also I tested today the same installation procedure on a USB. Now here is
the interesting part, in booting from a USB with the same settings and
configuration. The kernel loads successfully but a new error shows up
resulting in a system hang.
 ' Loading vmlinuz0 ... ok
Loading initrd0.img... ok
Probing EDD (edd=off to disable)... '
The problem starts when syslinux tries to load kernel file into the memory,
for some reason it tries to read the wrong addresses, or maybee it
calculates the addresses wrongly. I have tried several paritions sizes
<128M  >128M ... no success.
On your changelog, i see that you converted lots of assembly code into C,
somewhere there is the bug, which is not allowing for a successful load of
the kernel for the SD-Card case, and for the USB-case kernel is loaded but
again Probing EDD gets to compute the addresses wrongly.
there is a bug in the Syslinux-6.03 code, otherwise syslinux-4.06 should
have also shown similar issues, but it works like a charm.

Could you please point me to a documentation which allows for complete
compilation from scratch???
