I'm owner of Palm Tungsten E and very interested with porting Linux on it. Nowadays we have working kernel with touchscreen and SD support (thanks to Andrzej Zaborowski) which can be started using Garux (thanks to Romain Goyet). All this good, but we have very strange problem that can't be resolved without help from you. After kernel starts init process the system hangs. If I replace init by script which starts shell (sh from Busybox), it seems to be all right, but when I start any other program from shell, ls for example, it also hangs. As told Andrzej, "I did all kinds of memory tests and checked that there is no memory corruption. I also disabled all possible device drivers (running almost the original OMAP kernel without any patches) and probed all versions since 2.6.13-rc1 to 2.6.16-rc1, and the same behaviour was present." Then, I've debug Busybox init process and found where it hangs (for me): when it tries to reset signal handlers running actions from inittab. Call to function signal(SIGUSR1, SIG_DFL); hangs init process. Probably something is incorrect in kernel pathes for PalmTE... Can somebody help with understanding what is incorrect? Kind regards to all OMAP fans, Dzmitry http://epam.com http://linux.by
