Description Trond Danielsen 2007-04-27 15:16:19 UTC
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):

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.

Additional info:

Recent tests show that I also have to remove the mmc_core module too to prevent
the computer from locking up.

Comment 2 Richard Hughes 2007-05-24 10:40:39 UTC
Does this work with the latest kernel from rawhide? If so, please can you close
this bug. Thanks!

Comment 3 Trond Danielsen 2007-05-24 13:44:37 UTC
It seems to work now, which is great. The sdhci messages are gone from dmesg, so
everything seems to be fine. Bug closed!
