PRS-T1 Wifi error after standby

[uboot]

I struggling with enabling wifi after the device was in standby and I hope we'll find a solution with this thread for future reference.

Neither via Notification bar, nor via Settings app it is possible to activate Wifi. When activating the check mark, the device freezes for some time and then Wifi status says "Error".

After reboot I am able to enable Wifi, but as soon as I suspend the device and switch back on, it is stuck again.

In logcat it says "could not load wifi driver".

I do not want to do hard reset / sd recovery. There must be a way to fix this.

Any ideas?

Deleting /data/misc/wifi/wpa_supplicant.conf did not help.

The wifi driver seems to be compiled directly into the kernel. At least there is no wifi module in /lib/modules

I located the wifi module in /system/wifi but was unable to load it:

/system/wifi # insmod ar6000.ko
insmod ar6000.ko
insmod: init_module 'ar6000.ko' failed (Exec format error)

Look what dmesg says:

<4>mmcblk2: retrying using single block read(cmderr=0,dataerr=-110,stoperr=0)
<6>request_suspend_state: standby (0->1) at 61193633438918 (2012-02-23 13:48:03.031270790 UTC)

<3>end_request: I/O error, dev mmcblk2, sector 1634219

But this seems to be a software error, not hardware related, because when I booted into recovery console, dd if=/dev/mmcbkl2 of=/dev/null went through without errors.

After reboot, there where no more IO errors in dmesg.

Strange.


I am about to cook my own firmware now.

Freescale seems to offer updated kernel / Android images, let's see if they contain something usable.

Then I'll create my own initrd, system.img and data.img and incorporate Sony firmware updates. If anyone wants to join me, we should start a dedicated wiki page...

Exactly what I was waiting for...

Count me in!

I'm having the same problem.
Any progress in this?
Thanks.
