[opensuse-kernel] armv7hl kernel-default config have tegra20 serial output broken
Hello, I found that latest images for my armv7 board (paz00/ac100) which use kernel-default have kernel panic on start without any output to serial console, but serial output was working last time i tested image back in may. I cloned kernel-source git repo made sequence-patched kernel and recompiled it with enabling DEBUG_LL,TEGRA UART_A and EARLYPRINTK config options added to config/armv7hl/default config, but found that there is no ttyS0 output, only earlycon here is paste: http://paste.opensuse.org/31390203 Recompiling same kernel with multi_v7_defconfig config and same debug/earlyprintk options have no panics and normal serial output: http://paste.opensuse.org/13080662 Maybe kernel-default config require some extra tricks now to have serial output? I want to catch that panic. --- Best Regards, Misha Komarovskiy zombahatgmaildotcom -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-kernel+owner@opensuse.org

Have you tried to use kgdb? Does it not work too?

I'll try to find more details with kgdb, it seems problems on my tegra20 family board starts after 3.19 kernel. Russian is my native language, i will follow your guide, thanks.
I blame some kernel-default config option, because same kernel compiled with tegra_defconfig boots fine, but how to find which one?

Please take a look at function tegra_pmc_probe() (`git grep tegra_pmc_probe -- drivers/` to find the corresponding file). I'm guessing it tries to of_node_put() a NULL pointer or something else it shouldn't touch.

Thierry Reding pointed me to patch that fixes this oops in tegra pmc, it is already accepted for linux-next, http://patchwork.ozlabs.org/patch/493307/ and it should go to 4.1.7 or next stable release I just tested this patch with kernel-source stable branch and it fix boot for paz00 board, no panic anymore.

Doesn't ring any bell... You could try a more recent U-Boot, but I doubt it's related.

Tested Kernel:stable compiled with tegra_defconfig, image boot fine with such kernel, so it's again somehow connected to kernel config not to U-Boot.

Thanks for testing, I committed a fix on master together with some more serial cleanups. Should appear in Kernel:HEAD around tomorrow. And backported to stable branch. Looks like we need stricter patch review when I'm otherwise busy. ;) Cheers, Andreas -- SUSE Linux GmbH, Maxfeldstr. 5, 90409 Nürnberg, Germany GF: Felix Imendörffer, Jane Smithard, Dilip Upmanyu, Graham Norton; HRB 21284 (AG Nürnberg) -- To unsubscribe, e-mail: opensuse-kernel+unsubscribe@opensuse.org To contact the owner, e-mail: opensuse-kernel+owner@opensuse.org
