trying the most recent qtopia images (without any additional fixes). On
boot I mentioned some kernel oopses... here is one (phone was attached
via usb on boot to the laptop... and now remains attached although I use
wifi for terminal ssh)

full dmesg and output of ps auxw is at http://www.onerussian.com/Linux/bugs/qtopia.1/


logread is full of msg like

Jul 29 03:47:26 om-gta02 user.notice Qtopia: /opt/Qtopia/bin/quicklauncher: /usr/lib/libstdc++.so.6: no version information available (required by /opt/Qtopia/lib/libQtDBus.so.4)
full version is available again from the same url as above

3. also I mentioned that commands (like screen) start much faster on your image
than on om2007.2 (in ssh session). is that just my subjective impression?  on
2007.2 I thought it is just that device is slow, thus didn't check where
actually it spends time...  but now I know that it can be much more responsive
(I am not talking about GUI -- just ssh session)

4. in a list of contacts how to get quickly to some contact (lets say which
starts with letter L) -- help says to spell first letters but there is no
keyboard option available for me (I have time now where in some of the apps I
have a little keyboard icon).

N.B. You guys did/do great job with QTopia... hopefully Nokia will be kind to
opensource community ;-)
