SORRY, I made a mistake, I mean...

Booting the USB installer gives me a 'kernel panic - vfs unable to mount
root fs'


After struggling almost an hour, i got it working. I found that the content
of the syslinux.cfg is the culprit since I can boot without the
syslinux.cfg file and manually provide the boot parameter at boottime
