Syslinux - Dec 2017 - Isolinux 6.03 hangs under qemu with Intel HAXM accel

Hello friends!

HAXM is a hardware-assisted virtualization engine (hypervisor) that uses
Intel Virtualization Technology to speed up IA (x86/ x86_64) emulation on a
host machine running Windows or macOS.

Latest Isolinux 6.03 hangs under VM after "Main image LBA =...".

Please, help us investigate the root of the problem.
Bug on github: https://github.com/intel/haxm/issues/15

Thank you!

Any chance you could try 6.04-pre1?  Did you try any older versions
with success?  4.05, 5.10, 6.01, 6.02?

The last time we had this kind of report, IIRC (but I could be 
misremembering) it was related to building ISOLINUX with GCC 5+, and 
seen only on specific hardware/bios.
>From the linked report, the only potentially-relevant test would be 
with the latest Debian "netinst" ISO; the other ISO images mentioned
in
the github issue report at this time are using "old" (aka
"un-patched",
"non-maintained") versions of ISOLINUX (including the current
Debian's
"mini.iso", so Debian's "netinst" would be the smaller
one available at
the moment).


So, I would suggest testing with "isolinux-debug.bin" from Debian Sid 
or, even better, from Debian's "experimental" (and using _all_ the
relevant c32 files from the _same_ matching package version). For these 
tests, please use the binary packages for now, instead of building your 
own.

There are additional potential tests, but IMHO the above would be the 
first one, in order to start narrowing down the problem, if the real 
problem happens to be somewhere in ISOLINUX.


OTOH, perhaps this is more about the "ipxe" part of that github
report?
Could ipxe be left aside for the tests, so as to isolate the problem? 
The same could be asked about the SeaBIOS part (e.g. using a different 
bios file/version in qemu). All these factors are important, 
considering that this type of problems are mostly present in specific 
hardware/bios only.


Please note: only replacing "isolinux.bin" when rebuilding ISO images 
is _not_ a relevant test; the c32 modules _must_ match the exact same 
bootloader's version/build/package (i.e. they must be replaced too).

Regards,
Ady.

I've checked 4.05-pre7, 5.10-pre2, 6.01-pre6, 6.02-pre9 and 6.04-pre1 -
every time the same problem - hangs after "Main image LBA = ..."
