Re: [Bug 42387] 2.6.20: does not work after suspend

[Pedro Martínez Juliá]

I've got this error too but it's not related to suspend/resume. It's due
to direct power management. When a card goes to power save mode it
refuses to load firmware. I don't know how fix this bug.

My special case is:
- I'm uploading or download a big file (for example an ISO file)
- My card goes to power save due to hot. It happens earlier in summer
than in winter.
- Then, there is a firmware error (message seen in dmesg).
- IPW2200 driver tries to reload the firmare.
- Card refuses the firmware with error -22.

I don't know what happens. I saw a post somewhere telling that the
firmware loader does not find proper ucode. I saw posts with errors
reloading driver when the card is in power save...

You can try to unload the module before suspend and reload after resume.

Please try this and report your results.

[Bug 42387] 2.6.20: does not work after suspend

[Martin Rehn]

On a DELL D610 I get pretty much the same error as the original reporter
did, see below. My card gets into this broken state all the time,
notably whenever the machine is suspended, without me having fiddled
explicitly with the power state. To recover functionality I have to boot
with a different operating system. Sometimes it also works to repeatedly
load/unload the ipw2200 module, randomly pressing the Fn-F2 radio kill
switch button in between.

This is using the latest 2.6.20-13-generic in feisty. Thus, the bug is
not moot wrt 2.6.20, but the driver should really be fixed to set the
power state properly when loading. Please reopen the bug for 2.6.20;
this is a very severe bug for me; if it is not fixed for the feisty
release I will have to keep tracking the unstable kernel in the hope
that a fix comes along... I assume that I am not alone in this. Thanks!
