Novell ZENworks Configuration Management 11.4


Customer environment;
Windows 7 Pro SP1 (7601) on Lenovo 20FMS0KA00
ZAA Version:
FDE Version:
Boot hangs when a USB device is attached. BIOS and DMI settings have been verified on the devices.
The devices causing the boot hang (after a successful PBA authentication) include:
Docking stations, Printers, USB external hard drives.

After a successful PBA login, the user just sees a white screen and windows does not boot if the devices are connected during boot.


New Linux kernel required for proper function on this hardware model and chipset.
