Distribution: Slackware 9.1 Hardware Environment: Ibm R40 Software Environment: Any Problem Description: When I activate the S3 state, the machine stop (seems) properly. The "moon" icon is activating. But after that, it's completely blocked. Will stop to respond to any key (also a lont time pressure of power button). The only solution is to detach the power supply AND the battery and reboot. Steps to reproduce:
Distribution: any Hardware: HP nw8000 (see http://h18000.www1.hp.com/products/quickspecs/11798_na/11798_na.HTML) I think I observe the same bug on another notebook, HP nw8000 with ATI FireGL T2 card. I've tried the following kernels: stock 2.6.4 from SuSE 9.1 (because this one is ceritified by HP), 2.6.8-1 and 2.6.9-rc3 on Debian testing. In all cases, all modules except the required ones (i.e. IDE ones), including USB, sound, ... were unloaded although I did try it under X too, just in case. The symptoms are always the same: machine goes to sleep successfully but can't be woken up except by a hard reset. To reproduce, simply "echo mem > /sys/power/state". In this thread on ACPI mailing list: http://article.gmane.org/gmane.linux.acpi.devel/10113 I was told that it was probably a video card bug but I'm not sure about it because the machine is completely dead when power button is pressed after it suspends. The disk LED does light up but Caps Lock LED doesn't. Pinging it doesn't work neither. I'd be glad to provide any additional information and/or test any patches susceptible to fix this problem. TIA!
Is the problem still there with latest 2.6 kernel? If yes, can you make sure whether the problem is only with restore of the video (try connecting through network or serial after resume). If it is only the video problem, - Please try the options in Documentation/power/video.txt - Try the workaround in bug #3670
Latest stable kernel (2.6.9) solved the problem for me: my laptop is capable to resume after S3 now.
Thats good to know :). This bug is closed then. Vadim: If you still have S3 resume issues with HP nw800, please feel free to reopen this bug or open a seperate bug for that one.
Unfortunately updating to 2.6.9 didn't change anything for me. I'm currently using the Debian (unstable) version with everything compiled as a module and if I boot in single user mode and unload everything so that only intel_agp, agpgart, ext3, jbd and mbcache (the 2 last ones used by ext3) are loaded, I still have the same behaviour as before, i.e. after "echo mem > /sys/power/state" the machine seems to enter standby (screen goes black, no more network, keyboard leds don't work any longer) but the battery and AC led remain permanently on, while normally the battery one should be off and the AC one should be blinking slowly (i.e. this is what happens under Windows) and, most importantly, nothing except hard reset can wake it up. Worse, after hard reset the machine seems to start booting normally but nothing happens and I have to reset it the second time to be able to reboot. I have no idea how to explain this... As before, I'd be glad to provide any additional information, just please let me know what can I do as so far I remain stuck. Thanks!
Vadim: I have exactly same problem as you described, on my Compaq presario x1000. Few other systems have similar behavior to. I am clubbing all such reports under bug #3599, so that it can be addressed better. And closing this bug, as the original problem here was slightly different. Please follow up on bug #3599 from now on. Thanks.
