today I did a fresh install using the december release of the install media. Everything done 'to the book' (the install guide wiki page). Bootloader is syslinux.
When booting the freshly installed system, I get the syslinux menu, select Archlinux or fallback, things seem to be normal for a few seconds then everything stops. After some time I get a message that /dev/sda3 (which is the / partition) can't be found and I'm dropped into an emergency shell.
No LVM or RAID, just a single SATA disk with
sda1 = /boot (100M, ext2) sda2 = swap (2G) sda3 = / (~250G, ext4)
Partioning done with cfdisk.
The mkinitcpio.conf used is the default one, which seems to have all required hooks.
Everything in /boot/syslinux looks ok.
Any hints ??
