Centrino suspend/resume test result

Centrino suspend/resume test result

[Wang, Zhenyu Z]

Machine: Toshiba Satellite M20
Distribution: SuSE SLES9
Kernel: 2.6.5, build ipw2100 as modules

1. ipw2100 module load test ( version-0.41)
Sucessfully load hostap and ipw2100 module. Set static ip addr to eth1.

ping is also sucessful.


2.  S3 mode test
Entering S3 mode is sucessful in console, but not in X.
In console after resume, eth0 works normally.
dmesg says:

In X after resume, system hangs at "eth1: Using legacy firmware load."
No future action can be taken. Ping from other box failed.

3. S4 mode test
Entering S4 will hang system.
No screen output is captured.
ipw2100 debug says:
.... : Power cycling the hardware
.....:
eth1: Using legacy firmware load.

System hangs after this.

4. WEP not tested

Hi!

> eth1: Using legacy firmware load.

That will not work with S4. 

Try compiling ipw2100 non-modular. See how it fails.

Same thing happens during resume: what if disl wakes *after* ipw2100?
You may not access filesystem from resume() method.

BTW: who should I send ipw patches to? I send them once but got no reply...

BTW2: why is ipw not integrated into mainline? It seems to me enough people
work on it...
