gene, thank you for reporting this and helping make Ubuntu better. Could you please provide the information following https://wiki.ubuntu.com/DebuggingKernelSuspend ?
As well, could you please test the latest upstream kernel available following https://wiki.ubuntu.com/KernelMainlineBuilds ? It will allow additional upstream developers to examine the issue. Please do not test the kernel in the daily folder, but the one all the way at the bottom. Once you've tested the upstream kernel, please comment on which kernel version specifically you tested and remove the tag: needs-upstream-testing This can be done by clicking on the yellow pencil icon next to the tag located at the bottom of the bug description and deleting the text: needs-upstream-testing If this bug is fixed in the mainline kernel, please add the following tags: kernel-fixed-upstream kernel-fixed-upstream-VERSION-NUMBER where VERSION-NUMBER is the version number of the kernel you tested. If the mainline kernel does not fix this bug, please add the following tags: kernel-bug-exists-upstream kernel-bug-exists-upstream-VERSION-NUMBER If you are unable to test the mainline kernel, please comment as to why specifically you were unable to test it and add the following tags: kernel-unable-to-test-upstream kernel-unable-to-test-upstream-VERSION-NUMBER Please let us know your results. Thank you for your understanding. ** Summary changed: - rtl8192ce fails to recover after resume without shut down + 10ec:8176 rtl8192ce fails to recover after resume without shut down ** Tags added: needs-upstream-testing resume suspend ** Description changed: I am helping a friend with this laptop Satellite C655D (PSC0YU-03G02C) running Ubuntu 12.04 uname -a: linux 3.2.0-32-generic-pae #51-Ubuntu SMP Wed Sep 26 21:54:23 UTC 2012 i686 athlon i386 GNU/Linux - - It also uses the infamous rtl8193ce driver. My friend complained about frequent loss of connections and sudden system freezes. AMOF, Windows 7 was even worse to constantly shutdown by itself. So I suspected some hardware problem... - When I got a hold of it I saw the freezes with 3.2.0-23 kernel and spurious output of the rlt driver flooding the logs. After the upgrade to 0-30 and 0-32 freezes (due to the networking) stopped. However, what I found was that networking is lost completely when after resume from suspend. It was weird, that both wireless and wired interfaces just never worked. I tried to restart networking, network-manager services, rmomodding and modprobbing all modules related to rtl8193ce in many different orders. Nothing seemed to work, before I realizes that networking must be stopped before any other service prior to suspend and then started after every other service on resume. So here's a weird but working pm sleep hook /etc/pm/sleep.d/00_netwokmanager: + + It also uses the infamous rtl8193ce driver.
