Are you sure you have CONFIG_EARLY_PRINTK and earlyprintk also in your cmdline? > I don't know enough about that part of the kernel to debug it, so all > I can offer is a test result.

Can you try the following: - Use the current mainline kernel head - make sure you have DEBUG_LL and EARLY_PRINTK enabled in your .config - check that you have earlyprintk also in the kernel cmdline - no other serial patches applied If no serial output, please temporarily hardcode the values for your 7xx board in mach-omap1/include/mach/debug-macro.S for omap_uart_phys and omap_uart_virt. Maybe that will give some more clues. If you don't have any serial output with that, then try this: - reset some branch to 4f2c49fedf - make sure you have DEBUG_LL and EARLY_PRINTK enabled in your .config - check that you have earlyprintk also in the kernel cmdline - apply the following patch for the uncompress code That way you might be able to track down further where things break with the patches following 4f2c49fedf.
