SYMPTOMS
When you use a portable Windows Vista-based computer, you may receive a Stop error message that resembles one of the following:

STOP: 0x000000E4 (0x00000002, parameter2, parameter3, parameter4)

STOP: 0x0000000A (parameter1, parameter2, parameter3, parameter4)

Notes
 * The parameters in the Stop error message vary, depending on the configuration of the computer and on the issue type.
 * Not all &quot;0x000000E4&quot; or &quot;0x0000000A&quot; Stop errors are caused by this problem.

This problem occurs if the following conditions are true:
 * A USB camera device is integrated into the computer, or the device is connected to the computer through a USB cable.
 * You resume the computer from long-term suspend mode. For example, the computer has been suspended for 30 minutes or more.
 * The value of the computer's ForceHCResetOnResume registry entry is 0.



CAUSE
This behavior is caused by a timing issue between the Usbvideo.sys module and the Ks.sys module. When the issue occurs, the device object is deleted before a related work item is invoked.



WORKAROUND
To work around the issue, change the value of the ForceHCResetOnResume registry entry to 1.
