Description of problem: 
sdchi causes hard lockup when resuming from suspend-to-RAM.
If the sdhci module is removed before suspending, everything is fine.

Version-Release number of selected component (if applicable):
pm-utils-0.99.3-2.fc7
kernel-2.6.21-1.3116.fc7

How reproducible:
Every time

Steps to Reproduce:
1. Use the gnome-power-management applet to suspend the laptop.
2. Resume.
3. Wait for crash, which happends within the first ten seconds after resuming.
  
Actual results:
Everything locks up. Nothing works, have to hold the power buttons for several
seconds to force the laptop to shut down.

Expected results:
Resume normal operation.
