Description of problem:

My laptop (Compaq 6715b) no longer suspends after upgrade to kernel 2.6.35.12-88.fc14.x86-64. The error in pm-suspend.log is as follows:

/usr/lib64/pm-utils/pm-functions: line 295: echo: write error: Timer expired

Line 295 is where it tries to write "mem" to /sys/power/state:
do_suspend() { echo -n "mem" >/sys/power/state; }

Suspend works fine when booting with the previous kernel (2.6.35.11-83.fc14.x86_64)

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

Kernel: 2.6.35.12-88.fc14.x86-64
pm-utils: 1.3.1-4.fc14.x86_64

How reproducible:

Always

Steps to Reproduce:

Suspend the laptop by either closing the lid, choosing the corresponding option from the menu or running pm-suspend manually.
  
Actual results:

The screen flickers momentarily but the laptop is not suspended
