Most recent kernel where this bug did not occur: don't know
Distribution: Debian unstable
Hardware Environment: ASUS L2B Laptop
Software Environment: uswsusp 0.7
Problem Description:
After updating the uswsusp package from 0.6~cvs20070618-1 to 0.7-1 I cannot resume after suspending to disk. Kernel output is as follows:

Steps to reproduce:
Suspend to disk via s2disk. Power on.
Comment 1 Rafael J. Wysocki 2007-09-19 04:14:36 UTC
Is this 100% reproducible?
Comment 2 Cihan 2007-09-19 06:41:53 UTC
Yes, tried twice with same results.
Comment 3 Rafael J. Wysocki 2007-09-19 08:34:22 UTC
It looks like your resume binary has not been upgraded along with s2disk.

If you use an initrd, please make sure it has been regenerated with the new resume binary.  Also please check if the resume binary has been installed in the same place as with the previous version of the suspend package.
Comment 4 Cihan 2007-09-19 12:52:11 UTC
Thanks a lot. The reason was indeed that the update script did not take care of the initrd image.
Comment 5 Rafael J. Wysocki 2007-09-19 13:49:54 UTC
This is not a kernel bug, so I'm closing this entry with resolution "invalid".
