PM-Timer Bug in DMESG log

[Christopher Burke]

I have a message (listed below) in my dmesg log, and was hoping I could toss
this out to the community for more information.  I've tried searching
online, but couldn't find any concrete details.

 

The message is:

 

[    0.163416] * The chipset may have PM-Timer Bug. Due to workarounds for a
bug,

[    0.163421] * this clock source is slow. If you are sure your timer does
not have

[    0.163425] * this bug, please use "acpi_pm_good" to disable the
workaround

[    0.163463] * The chipset may have PM-Timer Bug. Due to workarounds for a
bug,

[    0.163467] * this clock source is slow. If you are sure your timer does
not have

[    0.163471] * this bug, please use "acpi_pm_good" to disable the
workaround

 

I have two questions related to this:

 

1.	How do I determine if my chipset has the PM-Timer Bug?
2.	Is this anything I need to be concerned about, or is it a benign
issue?

 

For reference, I am running Xubuntu Command-Line Server Feisty 7.04 on a
Dell PowerEdge 4400, Dual 866 Mhz processors.

 

Any information would be greatly appreciated.

 

Thanks much.

Chris
