usb storage does not show in /dev in latest pve 2.2

[totalimpact]

I am trying to use various usb drives as a backup destination, anything from a 16 gb sandisk usb flash to a 2tb drive will not detect properly, I have used 5 different devices with complete failure to show a device in /dev, does anyone have any idea what might be going wrong?

I am seeing an error in messages log and kern.log that seems to indicate an issue with the kernel module??:
usb_storage: disagrees about version of symbol module_layout

its a Dell R720:
/dev/sda: 1.1 tb raid10 array for raw LVM
/dev/sdb: 64gb sata ssd for OS
??? 1.5tb USB for backups...

pveversion: 2.2/3089a616

Odd - after a reboot everything works. I suppose I could have ran a aptitude upgrade, but I thought I rebooted after that.
