Can you remote access (for example, though ssh) the system after S3 resume? It maybe is just a blank LCD issue. The network card does not seem to come back up. I tried pinging the box from another machine after the resume and got no response. There might be a bug in ACPI code in file wakeup.S. The lgdt instruction is suggested by intel to add a DB 66h to become a 32bit instruction. Would you kindly try it to check if it is the root clause? I think it might also be worth to give it a try on other wakeup-fail system (not for display blank situation.) acpi4linux team has patched the comment #5 I wrote. Please check the latest acpi patch against 2.6.11 from http://acpi.sf.net filename: acpi-20050408-2.6.11.diff.gz Hope it helps. yours, Dennis please try 2.6.13 I'm still seeing this bug on my R31 with 2.6.14.3 and the suspend2-2.2-rc13 patch (no other patches). I have also hacked on my DSDT for this machine. Let me know what I can try to debug this problem. Is it possible you can try the patch at http://bugzilla.kernel.org/show_bug.cgi?id=2039? Thanks! Tried the patch but unfortunately I'm still seeing the same behavior. still an issue with linux-2.6.22.stable or later? Re: blank video, please try the workarounds in Documentation/power/video.txt please re-open if this is still a problem in linux-2.6.22.stable or later |
