Random Reboots; Minidump says kmixer

[Guest Marla]

We purchased 8 identical XP workstations around August last year and deployed

them in September through November last year. Each machine is running

identical software. We had 2 reboots in September, one in November, and 2 in

February, on different machines. Then on June 12 we started having frequent

random reboots. They seem hardware rather than software related because the

machine doesn't log anything going down, only coming back up.

 

The two error messages we are getting are: Error code 8086 with all

parameters 0s or error code 100000d1 with parameters 28, 2, 0 and f7b51be7.

Each minidump always refers to kmixer.sys. We are only using on-board audio.

 

We have reseated the memory and cleaned the cpu heat sink. We have deployed

SP3 (seemed to make things worse, but still random) and then updated drivers

related to video and audio, although most were already the latest available.

We also updated the BIOS. The reboots continue. These are very critical

machines. We have had 13 reboots now in just over two months. Any ideas on

what we should try next?

I googled kmixer.sys and found several recent references to malware.

 

I used the command prompt to see how many bytes kmixer.sys contained.

172,416 for Windows XP SP3. Use the command prompt to compare the sizes.

Type the following commands at the prompt and then <enter>

cd is short for change directory and dir is short for show directory.

 

C:\Documents and Settings\Username>cd C:\windows\system32\drivers enter

 

Then at C:\windows\system32\drivers>dir <enter>

 

There aren't that many files so you can scroll up to kmixer.sys

and see if the size of the files match up, mine and yours.

 

Also if you are use XP Home I don't know for sure if the size of

the kmixer.sys files are the same as on the Pro version. You could

check the file size of kmixer.pro on all 8 machines and compare them.

I don't think windows explorer reports file sizes in the exact standard.

Stephen:

 

Actually, 5 of the 8 XP Pro PCs are at SP2, and three have been upgraded to

SP3 in the process of troubleshooting this issue. The ones at SP3 are

rebooting more frequently than the others, although it is still random. The

three at SP3 match your file size, and the rest are all the appropriate file

size for SP2 (171,776).

Stephen:

 

This article is actually why we applied SP3 to the 3 PCs that were rebooting

most often. So we are at a revision of these files higher than shown in this

article.

 

Do you know if SP3 can be uninstalled? I've considered rolling it back and

just applying this patch.

Which means you are using genuine Windows OS Software with proper

licenses :)

Re: Random Reboots; Minidump says kmixer

 

Hello,

 

I would firstly suggest that you contact the device (audio device,

specifically) manufacturers to see if the device or device drivers can work

well with Windows XP, or if there are any known issues (or updates) on the

specific device or drivers. I saw that you had updated the driver, however,

I would still suggest that you contact the manufacturers for detailed

information.

 

Saying this is because, based on some research, I found this problem (error

code 100000d1 and kmixer.sys) might be caused by the incompatible device or

driver, or some driver problems (bugs), and usually could be resolved by

updating the driver.

 

If you are not sure about this, I would highly suggest that you contact our

Microsoft Customer Service and Support (CSS) to find out the root cause.

You can speak directly with a Microsoft Support Professional to analyze the

crash dump. For a complete list of Microsoft Product Support Services phone

numbers and information about support costs, please go to the following

Additionally, if you want to remove Windows XP SP3, you can try the

following KB article:

Good luck.
