Hi Martin,
We have 13 machines passed the 24 hours runin test with OS26.
10 are 4G SKU and the others are 8G.

Still have 3 8G machines doing the runin test.

We confirmed this version fixed many issues as below:
#11392, #11528, #11576, #11546, #11595, #11536, #10831, #10893, #11496, #11321

Subject: 11.3.1 development build 26 for XO-1.75

This build merges kernel 3.0.17 (which reworks the MMC layer), and includes fixes in EC communication, audio recording & playback, WLAN during suspend/resume and serial port driver. It also downgrades some graphics libraries back to OS24 versions.


 - Under GNOME we have a new cursor theme that looks much better.

 - Thanks to the suspend/resume WLAN fixes, this build has aggressive suspend resume enabled under normal usage. The resume path is still a bit slow, but generally works.

 - Wake-on-LAN is not yet working -- WLAN stays associated to an access point during SoC sleep, but will not wake to a ping or tcp connection.
