 |
|
TuxOnIce 2.6.24-r3 and Gentoo 2.6.23-r9 can't bring my laptop out from the S3 (Suspend To Ram) mode,
if i do an
| Code: | | echo "mem" > /sys/power/state |
Or simply if i use KPowersave and i do a "Suspend To Ram" i can see my laptop going in S3 mode, and the power led starts blinking.
BUT when i push a key (To wake the laptop) the led stops blinking and stays active, the cpu fan starts, but the monitor stays off.
Thank you for any hint/help.

Some upgrades,
i did this:
| Quote: | - enable PM_DEBUG, and PM_TRACE
- use a script like this:
#!/bin/sh
sync
echo 1 > /sys/power/pm_trace
echo mem > /sys/power/state |
i unloaded all the modules and services, then i started the script.
Resume didn't work, and this is what i found in dmesg:
| Code: | Magic number: 0:191:890
hash matches drivers/base/power/main.c:76
hash matches device 0:0:0:0
hash matches device 0000:00:1f.3 |
Some other outputs:
| Code: | ivito ~ # lspci | grep 00:1f.3
00:1f.3 SMBus: Intel Corporation 82801G (ICH7 Family) SMBus Controller (rev 02) |

Ok, the device 1f.3 WAS an unknown device, now i installed i2c-i801 and it's ok, but suspend can't resume the pc anyway.
Now it locks there:
0000:00:1c.1:pcie02
but D'OH it's a pci-ex device and lspci reports that 00:1c.1 is the "PCI Express Port 2", how i can see what's it?

Updates:
I discovered (using lshw) that there's the wireless interface connected to pci express port 2.
So it's not enought to remove the iwl3945 module, what else could i try to make this suspend works?????????????
Thank you for any help!!!
