the network still works, doesn't it?
Please attach the dmesg output when LCD is switched off.
Comment 2 Zhang Rui 2008-09-22 00:59:02 UTC

Comment 5 Cijoml Cijomlovic Cijomlov 2008-10-11 13:23:47 UTC 
Hi Zhang, just tested (wifi connection) and laptop doesn't respond. I tried final 2.6.27 and it is same...
Comment 6 Zhang Rui 2008-10-30 00:49:45 UTC 
so the laptop fails to suspend.
As this is a regression between 2.6.26.3 nad 2.6.26.4
it would be great if you can run git-bisect to find out which commit introduces this bug.

there are several links about how to use git-bisect. :)
