Today when I booted up my system, it hung with the following message:
note: scsi_eh_3[57] exited with preempt_count 1
tsc: Refined TSC clocksource calibration: 2699.999 MHz
Switching to clocksource tsc
then it just hangs
I can't even get into a terminal to see what is going on. Is there a boot option I can set in GRUB? I'm at a loss and I need to access my files today.
thank you

If I add acpi=off , then the machine boots until it would normally show the gdm login screen, instead it flashes the terminal login screen on and off. It stays like this. I cannot switch to another virtual terminal. The machine remains unresponsive.

Same problem here after my upgrade yesterday. My screen works without acpi, but no second screen, usb, powermonitor, ... Something to do with the systemd upgrade I guess...

Owkey ... Found a workaround/fix...
Seemed a module was timing out on boot or something, so changed my mkinitcpio.conf, left out the pata modules/hooks as I only have sata-drives. Ran mkinitcpio again, and that worked perfectly...
Still figuring out why this is happening ...
As root:
edit /etc/mkinitcpio.conf
remove pata_acpi from MODULES
remove pata from HOOKS
make a backup from your /boot/kernel26.img
run mkinitcpio -c /etc/mkinitcpio.conf -g /boot/kernel26.img
reboot
Hope this helpes somebody with the same problem ...

Same problem. Any progress on tracking down the root cause?
Update:
Found another thread on this same issue: https://bbs.archlinux.org/viewtopic.php?pid=1177937
There is a kernel bug filed: https://bugzilla.kernel.org/show_bug.cgi?id=49151
The most reliable solution is probably to downgrade kernels until it's fixed. stopstop's method also worked for me, though I blacklisted the module by appending modprobe.blacklist=pata_acpi to the kernel line in my grub config.
