jim, have you double checked with TI folks in linaro-android channel on the exact kernel/binary version combination to use? when i talked to them they were quiet helpful. only problem was that the had not pushed the defconfig yet and that there were build failures for kernel. anyway, first step is really to make our leb-panda build use a) their proposed kernel tree/version and b) include their exact binaries. then when we have a build we can daily show we can probably get them to fix things or at least get ideas from them on what might be wrong.
hi Alexander,
The perfect one I knew is the package from Froyo_L27.8.2_Graphics-1.0-Linux-x86-Install.
Our OESF friend, sola, indicated before: http://blog.sola-dolphin-1.net/archives/3173852.html
I was using this kernel tree: https://github.com/sola-dolphin1/OHA-Android-2.3_r1.0/tree/master/kernel
However, after switching to p-android-omap-2.6.38 (omap-kernel), I encountered the same problem as you.
According to git log:
commit 2cf3c35decc02cc198d835596e0393490ef3414e Author: seonkon.choi seonkon.choi@ti.com Date: Wed Apr 13 10:20:20 2011 +0900
OMAP3: HWMOD: Fixed bugs of GPU hwmod.
The GPU(SGX) has a type2 SYSCONFIG at 0x50000000 + 0xfe10.
Needed for SGX-KM 1.7.17.4403.

Also, the kernel configuration:
$ grep SGX .config CONFIG_SGX540=y # CONFIG_SGX_REV110 is not set CONFIG_SGX_REV120=y CONFIG_SGX_540_BUILD_RELEASE=y
I am checking the kernel messages triggered by CONFIG_SGX_540_BUILD_DEBUG.
Thanks, -jserv
