How To Fix Windows Vista Stop 0x9F and 0xB8 Error

Before attaching an IEEE 1394 device to a Windows Vista-based computer, confirm the Vista Update KB936150 has been installed successfully.

According to Microsoft Knowledge Base article KB929762, a Windows Vista-based computer will likely stop responding if you wake it up from Sleep mode while an IEEE 1394 device is physically connected. The IEEE 1394 device could be a Maxtor One Touch II 300GB model external hard disk, Apple iPod, etc.

To address this Vista-IEEE 1394 issue, Microsoft released Vista Update KB929762 on Jan 2007 for those who encounter error message that resemble

*** STOP 0x0000009F (parameter1, parameter2, parameter3, parameter4)
DRIVER_POWER_STATE_FAILURE

However, the Vista Update KB929762 was failed again when a delayed procedure call (DPC) routine tries to perform an unauthorized operation (as in KB936150). The Vista-based computer with KB929762 installed will stop responding too when waken up from Sleep mode, with another error message that resemble

*** STOP: 0x000000B8 (parameter1, parameter2, parameter3, parameter4)
ATTEMPTED_SWITCH_FROM_DPC

Six months after the release of KB929762, Microsoft advice all Vista-IEEE 1394 owners who encounter the Stop 0xB8 error message to install Vista Update KB936150 that contains latest Sbp2port.sys version 6.0.6000.20614!

Note:

To ensure Windows Vista always running in good shape, remember to turn on Windows Update and Windows Error Reporting service. Otherwise, you’ll have to ask Google a solution for the error code and manually download the Vista Update.

For non-IE7 users (who prefer Firefox, Opera, Safari, etc), I hereby enclose the direct download links of Vista Update KB929762 and Vista Update KB936150.

    I wish those updated would actually work…
    I have a Maxtor One Touch 750GB drive and the darn thing causes crashes like you wouldn’t believe. All latest updated installed of course.
