Sleep/resume in FreeBSD 9 on a ThinkPad

Sun Nov 18 18:48:35 UTC 2012

Hello again,

I hope I have covered in my tests all the suggestions you guys offered. The
result is the same: on resume, something happens, and then the computer
restarts.

Here is the detailed description:

###############################################
1. Test: BIOS update. Result: NOTHING CHANGES
###############################################

Matt, thanks for indications here, as Lenovo's website confused me to think
that the .iso file works only on Windows. Indeed, they have a small note
below that basically says that is OS independent.
So I used cdrecord (thanks for this one too) and it worked. Now I have an
up-to-date BIOS, and it's nice to know how to do that, but the resume
behaves the same.

########################################################
2. Test: turn off usb devices. Result: NOTHING CHANGES
########################################################

I powered off whatever devices I could find with usbconfig that were
power-off-able

Details of the test

usbconfig

ugen0.1: <EHCI root HUB Intel> at usbus0, cfg=0 md=HOST spd=HIGH (480Mbps)
pwr=SAVE
ugen1.1: <EHCI root HUB Intel> at usbus1, cfg=0 md=HOST spd=HIGH (480Mbps)

sysctl hw.pci.do_power_nodriver=3
hw.pci.do_power_nodriver: 0 -> 3

3. Test: disable stuff in BIOS. Result: NOTHING CHANGES
#########################################################

Did not find to much to disable in BIOS. The only stuff I could disable
were:
Wake on LAN
Wireless LAN

Which I did, I disabled them, tried sleep command, same result.

#######################################################################
4. Test: Kill X, turn off usb devices, unload the modules I could, all
in one test. Result: NOTHING CHANGES
#######################################################################

# The modules loaded are:

kldstat
Id Refs Address            Size     Name
 1   28 0xffffffff80200000 11cd9b0  kernel
 2    1 0xffffffff813ce000 45090    linux.ko
 3    1 0xffffffff81414000 6600     cuse4bsd.ko
 4    1 0xffffffff81612000 328d     ng_ubt.ko
 5    1 0xffffffff81616000 8b3d     ng_hci.ko
 6    3 0xffffffff8161f000 a79      ng_bluetooth.ko
 7    5 0xffffffff81620000 8e12     netgraph.ko
 8    1 0xffffffff81629000 b4a2     ng_l2cap.ko
 9    1 0xffffffff81635000 1695e    ng_btsocket.ko
10    1 0xffffffff8164c000 1ba9     ng_socket.ko
11    1 0xffffffff8164e000 64a91    radeon.ko
12    1 0xffffffff816b3000 139a7    drm.ko

I was able to unload the following: cuse4bsd.ko (/boot/loader.conf)
ng_ubt.ko, radeon.ko, drm.ko

The rest couldn t be unloaded: Device busy. Should I see what they are
and try to tell /boot/loader.conf to not load them ???

##################################################################
5. Compile a kernel with: no uhci, ohci, ehci, or xhci.
Result: NOTHING CHANGES
#################################################################
It was the first time to compile a kernel, it was fun to learn how to
do it, and I will probably continue doing it :)

Of course, after booting with this configuration, I guess I had no usb
support. usbconfig command did not return anything. So Matt, I think that
is even 'better' than powering off usb devices :)
I haven't even tried to log in to KDE, I just went in console and try the
sleep command. Same result.

cat /sys/amd64/conf/NO_UHCI

include GENERIC
ident NO_UHCI

nodevice                uhci            # UHCI PCI->USB interface
nodevice                ohci            # OHCI PCI->USB interface
nodevice                ehci            # EHCI PCI->USB interface (USB 2.0)
nodevice                xhci            # XHCI PCI->USB interface (USB 3.0)

####

I am not a C programmer, but I think somehow I should be able to rely more
on debugging the matter, and maybe with your help, if it is not to
complicated, to interpret the results, get close to the problem's root
cause and squash it.

Thank you guys for your help so far, let me know if you have a recommended
path to go further.
