I have an interesting problem on my laptop: about 1 in 3 times during
boot, the initrd fails to find the root file system, which is located
on LVM. I'm quite sure that this started after upgrading to linux
3.5.0-1

Booting via EFI on Dell Latitude E6410, disks configured in AHCI mode,
x86_64, using systemd.
Root FS is not encrypted, but I'm using /etc/crypttab for other file systems
Kernel command line: /vmlinuz-linux root=/dev/mapper/larcvg-larc--root ro  quiet

Output during failed boot:

No volume groups found
[ ... waits some seconds ... ]
ERROR: device '/dev/mapper/larcvg-larc--root' not found. Skipping fsck.
ERROR: Unable to find root device '/dev/mapper/larcvg-larc--root'.
You are being dropped to a recovery shell
...

/dev/mapper is empty, but when I run 'lvm vgchange -a y' then all
devices successfully appear.

/etc/mkinitcpio.conf:
MODULES="ahci ext4 dm-crypt aesni-intel"
BINARIES=""
FILES=""
HOOKS="base udev autodetect pata scsi sata lvm2 filesystems usbinput fsck"

There aren't any obvious causes in dmesg output either. There are some
differences in EFI stuff, SATA disks are discovered in a slightly
different order and there's an additional message "spurious 8259A
interrupt: IRQ7." during a successful boot.

Here's a diff of dmesg (timestamps removed):
