[Galaxy S I9000 Android Development] Timo Schmidt:
Sorry to bother again, but I made some "interesting" discoveries regarding my problem which lead me to the conclusion that something with my system-partition is wrong:

To solve the problem with the RFS-conversion I installed Speedmod on a ext4-Galaxy S i9000 with Talon 0.3.1 Kernel. After rebooting I started my Galaxy S in recovery mode (Speedmod CWM 2.5) and disabled the lagfix. After Speedmod converted my ext4 filesystem back to RFS (checked it via "mount" in Terminal Emulator) I restarted the device and reinstalled Talon 0.3.1 Kernel in Speedmod CWM.

This is where the strange things begin: After installing Talon the first boot took 20 minutes or so (I think the rebuilding of the dalvik-cache needed some time too), sticking at the "Talon" Logo. There was no voice which announced a lagfix-activation.

After these 20 Minutes everything went fine and my device started as usual. So i went in to the voodoo control app to check if the lagfix is fully enabled. The control app said "Ext4 Lagfix active on /cache /dbdata and /data - but not for /system. In the "Lagfix preferences" the two checkboxes "Ext4 conversion" and Ext4 /system where enabled though. To check if system is really ext4 enabled I checked it in Terminal Explorer via "mount". And no - the line

"/dev/block/stl9 /system rfs ro,relatime...."

showed that ext4 is not enabled for this partition.

So I decided to convert back to RFS with Talon via the voodoo app. But after restarting nothing happened - only the two checkboxes in the voodoo-app are now disabled.

Next thing I did, was to control the voodoo logs (history) under /sdcard/voodoo:

The bold log-lines are strange or alarming!

Sorry for writing such a long post, but there is definitively something wrong with my system-partition it seems...

My hope is that you - existz - or someone else who has very good knowledge in the Android-System can help with this strange thing.
