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? > --- > Best Regards, > Misha Komarovskiy > zombahatgmaildotcom > > > On Wed, Aug 5, 2015 at 3:27 PM, Matwey V.
