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