Twice now in as many months I have been the proud recipient of a BSOD on XP. The crashes were identical to each other with only various addresses being different (modules loaded into a different location and the like). They appear to have been caused by a bug in w29n51.sys; the crashes are of the IRQL_NOT_LESS_OR_EQUAL (a) variety. w29n51.sys is the "Intel® Wireless LAN Driver". Admittedly, I'm running a version that is likely not the latest. But it is interesting that googling the relevant stack entries (w29n51+0x1291, w29n51+0xa6af) turns up no hits. Also of interest is that the driver file is larger than 3 MB - more than 3 times the size of the next largest driver file in %systemroot%\system32\drivers... Strings does show a large number of verbose log-type messages that one can presumably cause to be logged via some configuration setting, as well as "tabular" data.
Of course, it is also disturbing that at the time of these crashes, the wireless hardware was disabled on this laptop...

After the previous BSOD in Vista, I logged in to Vista interactively as an administrator (I usually run as a standard user), and I was greeted with a dialog informing me about a "serious error" or the like. I chose to check for updates to the problem. What came back was more than I expected, but not really all that helpful for my particular situation.
Problem caused by ATI Graphics Driver
This problem was caused by ATI Graphics Driver.
This program was created by ATI Technologies, Inc.. ATI Technologies, Inc. does not currently have a solution for the problem that you reported.
Recommendation
--------------------------------------------------------------------------------
The following troubleshooting steps might prevent the problem from recurring.
Download and install an updated version of ATI Graphics Driver from one of the following locations:
Microsoft Update
ATI Technologies, Inc.
If an updated driver is not available for ATI Graphics Driver, check with your computer manufacturer.
If you are running the latest version of ATI Graphics Driver, contact ATI Technologies, Inc. for your support options.
Additional information
If this problem continues to occur after installing the latest product updates, we recommend you get assistance and troubleshooting information directly from ATI Technologies, Inc..
--------------------------------------------------------------------------------
I am running the latest driver, and ATI has
discontinued the Radeon 9600 Pro. Not a big deal, as the problem has only happened twice. Of course, I would rather that it not happen at all...

Recently, after resuming my Vista laptop from hibernation, I was greeted with a rather strange wait, followed by a blue screen of death. Analysis of the dump yielded the following:
THREAD_STUCK_IN_DEVICE_DRIVER (ea)
The device driver is spinning in an infinite loop, most likely waiting for hardware to become idle. This usually indicates problem with the hardware itself or with the device driver programming the hardware incorrectly.
If the kernel debugger is connected and running when watchdog detects a timeout condition then DbgBreakPoint() will be called instead of KeBugCheckEx()and detailed message including bugcheck arguments will be printed to the
debugger. This way we can identify an offending thread, set breakpoints in it, and hit go to return to the spinning code to debug it further. Because KeBugCheckEx() is not called the .bugcheck directive will not return bugcheck
information in this case. The arguments are already printed out to the kernel debugger. You can also retrieve them from a global variable via
"dd watchdog!g_WdBugCheckData l5" (use dq on NT64).
On MP machines (OS builds <= 3790) it is possible to hit a timeout when the spinning thread is interrupted by hardware interrupt and ISR or DPC routine is running at the time of the bugcheck (this is because the timeout's work item can be delivered and handled on the second CPU and the same time). If this is the case you will have to look deeper at the offending thread's stack (e.g. using dds) to determine spinning code which caused the timeout to occur.
Arguments:
Arg1: 870246b8, Pointer to a stuck thread object. Do .thread then kb on it to find the hung location.
Arg2: 00000000, Pointer to a DEFERRED_WATCHDOG object.
Arg3: 00000000, Pointer to offending driver name.
Arg4: 00000000, Number of times this error occurred. If a debugger is attached, this error is not always fatal -- see DESCRIPTION below. On the blue screen, this will always equal 1. Debugging Details:
------------------
PEB is paged out (Peb.Ldr = 7ffd800c). Type ".hh dbgerr001" for details

Seems that the hardware was messed up, as I had to force the laptop to power down twice during subsequent boots, in order for Vista to make it to the logon prompt.

With a new major release of a new operating system, one would think that there is so much new stuff to look at and play with that nobody would obsess over an icon. That is not the case, apparently, as opinions flare over Apple’s representation of Windows PCs in Leopard.
One of the new features in Leopard is easy access to computer on the local network, which show up, conveniently, on the left side of the window. Like with nearly all things, Apple has paid a lot of attention to the feature, to the point that the icons of each and every computer there tries to match what the computer product actually looks like on its owner’s desk. With Macs this is easy, since Apple can quickly identify the exact model of the networked machine, but with a PC, things are a bit more complicated since there are so many makes and parts in them. To solve this, Apple represents all Windows PCs as a beige monitor with a Blue Screen Of Death (BSOD). (more…)
