2.6-test4 problems: suspend and touchpad

2.6-test4 problems: suspend and touchpad

[Nicolae Mihalache]

Hello!

I have a Acer Travelmate 800 laptop and I'm using SuSE Linux 8.2 on it.
I tried recenly to install linux 2.6 and I observe two main problems:
1. The touchpad(synaptics) does not work. In kernel 2.4/X11 4.3  it 
works very well both as a generic ps2 mouse or as a synaptics (using X11 
driver for synaptics). The kernel 2.6 seems to have included a driver 
for the synaptics device, it is detected at boot, but it does not work 
in X (I guess it must be some kind of conflict between X11 driver and 
kernel driver?).

2. suspend/resume. With version 2.6test2+acpi patch both swsusp and 
"echo 3 >/proc/acpi/sleep" worked, being able to somehow successfully 
resume. In version 2.6test4 there is no /proc/acpi/sleep and swsusp 
hangs somwhere during an IDE call (I can hand-copy the trace if needed).

Any ideea?

Would you please try the latest -mm patch (2.6.0-test5-mm1, I believe) and 
report your findings? 

Thanks,

Well, the 2.6.0-test5-mm1 does not compile on my system (SuSE 8.2, gcc 
version 3.3 20030226 (prerelease) ):

mm/slab.c: In function `ptrinfo':

Ok, I solved the compilation problems and with this kernel swsusp does 
not hang anymore.
The resume works however the network adapter (Broadcom 4400) does not 
even when restarting the network.
ifconfig eth0 shows very big counters:
eth0      Link encap:Ethernet  HWaddr 00:C0:9F:26:C7:15
          UP BROADCAST NOTRAILERS RUNNING MULTICAST  MTU:1500  Metric:1

Any ideas? Maybe the driver for this network card does not (correctly) 
implement suspend/resume ?

Pretty probable. Look at the driver sources, and if there's no _suspend method, write one.
If you ifconfig down before suspend, does it help?

It does not. Could you please try removing the module before you suspend? 

Thanks,

Yes, removing and readding the module does the trick.
Unfortunately I've seen that something else does not work after resume: 
my USB mouse.
But for some reason I can not remove the usbcore module, the kernel says 
it's in use.

Now, how can I help to solve these problems? Is somebody working to 
solve these problems or should I try to solve them myself (at least with 
the Broadcom 4400 driver) ?

Thanks,

I see that the mouse is not even powered. It's an optical mouse and the 
light stays switched off.

USB suspend/resume does not currently work. It worked for uhci in
-test3, but it never worked for ohci.

Network driver should be reasonably easy to do; so please help :-).

AFAIK, there is no one working on either of these issues. I would
recommende contacting the maintainers about what it would take to
implement suspend/resume. They should hopefully have an idea of how to go 
about it, if not able to do it themselves.

Thanks,

You need a new version of the X11 driver:
