Hardware and software info
dmesg before suspending |
||
Will you please do the following test on the latest kernel? a. kill the process which is using /proc/acpi/event(using the command of "lsof /proc/acpi/event") b. echo mem > /sys/power/state; dmesg >dmesg_after; sync; c. press the power button and see whether it can be resumed. d. if it can't be resumed, please reboot the system and see whether the file of dmesg_after is created. If it is created, please attach it. thanks. Created attachment 22865 [details]
dmesg before suspending
dmesg_after is not there after reboot.
Kernel is NOT tainted.
Hi, Artem
Sorry for the late response.
From the test it seems that the system can't be resumed. Maybe it is related with BIOS. Unfortunately now we have no idea about this issue.
And we see this issue on many laptops.
This bug will be marked as the duplicated of bug 11255.
Thanks.
*** This bug has been marked as a duplicate of bug 11255 *** *** Bug 13225 has been marked as a duplicate of this bug. *** Zhang, Speaking frankly I don't know what to do with this bug, because my PC (not a laptop BTW), doesn't resume even with kernel 2.6.28.10 (as opposed to the initial bug report). I'm closing the bug, until I have enough time to remove all peripherals one by one in order to find a piece of hardware which makes the kernel unable to resume (probably I will even have to disable PAE support in kernel) - I ain't an ACPI specialist :( I'm greatly disappointed because Windows XP SP3 on the same PC works just fine. It's not a duplicate of bug 11255. I initially opened bug 13225. (See numbers are very similar). I'm sorry for the mess. Hi, Artem
Is the same box used in the bug 14041 and 13225?
From the info in bug 13225 it seems that the box can be resumed. But the screen is not restored correctly. Right? How about using the vbetool?
From the log in comment #2 it seems that there is no file of dmesg_after after suspend/resume. So I mark it as the dup of bug 11255.
Thanks.
Yes, it is the same box. Actually you have forgotten to mark this bug as a duplicate - ok, I'll do that. *** This bug has been marked as a duplicate of bug 11255 *** Closing it as invalid - my computer cannot resume even with Windows XP SP3. Possible causes: 1) Broken motherboard (I have a slightly inflated capacitor); 2) Broken BIOS (I have a beta version installed); 3) Broken other hardware (not sure if it's possible - but who knows). |
Created attachment 22816 [details] Hardware and software info The computer suspends successfully but then I cannot wake it up - it powers on but the screen remains black, network interfaces are inaccessible, keyboard buttons are not working (leds cannot be changed by pressing Caps Lock/Scroll Lock/etc). System fan after resuming is roaring (before suspend I make `echo 70 > /sys/devices/platform/it87.656/pwm2` to slow it down). Relevant hardware information is attached (as well as .config/dmesg/lspci/etc). This happens with or without VESA console. There are no working kernels.
