Package: pm-utils Version: 1.3.0-3 Hello, my Asus EeePC 1000HE as well as Hans's 1005HGO are no longer able to resume from hibernation since upgrading pm-utils, linux-image-2.6.32-5-686, and grub-pc.
Resume had been working on November versions of these packages (and many iterations prior to that), version details below. Unfortunately Asus EeePC does not have a serial port and I'm unfamiliar with debugging hibernation/resume. The following mail was sent to debian-eeepc-devel: Hans-J.

Thanks Hans, I will, unfortunately I have yet to figure out how to debug resume to offer more details. -- System Information: Debian Release: 6.0 APT prefers testing APT policy: (500, 'testing') Architecture: amd64 (x86_64) Kernel: Linux 2.6.32-5-amd64 (SMP w/2 CPU cores) Locale: LANG=en_US.UTF-8, LC_CTYPE=en_US.UTF-8 (charmap=UTF-8) Shell: /bin/sh linked to /bin/dash Versions of packages pm-utils depends on: ii console-tools 1:0.2.3dbs-69.1 Linux console and font utilities ii powermgmt-base 1.31 Common utils and configs for power Versions of packages pm-utils recommends: ii procps 1:3.2.8-9 /proc file system utilities ii radeontool 1.6.1-1 utility to control ATI Radeon back ii vbetool 1.1-2 run real-mode video BIOS code to a Versions of packages pm-utils suggests: ii cpufrequtils 007-1 utilities to deal with the cpufreq -- no debconf information -- Gerald Turner Email: gtur...@unzane.com JID: gtur...@unzane.com GPG: 0xFA8CD6D5 21D9 B2E8 7FE7 F19E 5F7D 4D0C 3FA0 810F FA8C D6D5
