Mostly the system works, but bluetooth has stopped working.  However, I don't
know if this message is related to that.  I've logged a seperate bug with the
bluetooth module in case it is a seperate problem.

Version-Release number of selected component (if applicable):
2.6.11-1.1236_FC4


How reproducible:
always on waking


Steps to Reproduce:
1. boot fedora on thinkpad t42p (set boot parameter acpi_sleep=s3_bios)
2. echo 3 > /proc/acpi/sleep
3. wake the computer
  
Actual results:
debug message


Expected results:
no debug message
