Agree.

Well, if you have a thumb2 binary issuing calls to the standard (non-thumb) libc etc, there's going to be switching. Or am I missing something?
If you use VFP then there is no difference whether it is pure ARM, ot thumb2, in either case you have a penalty if the code is not well optimized. The major difference between thumb and thumb2 is that thumb2 is almost as fast as ARM, and AFAIK there is no penalty for mixing ARM/thumb2 code.

Info: with 2.9M available rootfs, i still have to move '/usr/share/themes/beta' (7.1M) and '/usr/share/nokia-maps' (8.1M) back. This is after removal of kernel-power.

Some observations:
-2.6.28.10-cssu1 is running on 850 Mhz
-you have to install kernel-cssu-flasher
-cat /proc/cpuinfo doesn't show thumb2
-kernel too old to chroot into ubuntu 12.04

But of course, it is the same old KP50 with some modification, read the OP.

You only have to install kernel-cssu-flasher if you did not update in HAM/did not do apt-get update, so an older version of mp-fremantle-community-pr is used

You need to boot into the CSSU kernel, using CSSU thumb.

(Side note: this is incredibly promising. Wish both of these get merged into CSSU-main and KP.)

Well, again, you MUST have kernel-cssu flashed (or kernel-cssu-bootimg booted via u-boot) in order to have stable thumb2, there is just no other way.

You could try a full power cycle, sometimes the device does not cleanly reboot and SGX driver almost freezes the system

Thumb2 support is going in next KP for sure. While for CSSU-main, well, you'd better ask the maintainers :P
