Hello Matwey, I hope soon to be able to collect panic log, as tegra20 serial output is fixed in kernel-source now.
Panic happen before simple serial console started, but i made package of kernel-default with tegra DEBUG_LL enabled and now i have panic logs: http://paste.opensuse.org/15729922, log with initcall_debug http://paste.opensuse.org/76504505
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.
Current image openSUSE-Tumbleweed-ARM-JeOS-paz00.armv7l-1.12.1-Build331.3.raw.xz now include kernel 4.2.1 which have tegra pmc fix included, kernel start to load now but i have new different oops, here is log http://paste.opensuse.org/3794617
