Hi,
I've just tried to boot the current stable kernel v5.2.6 (and also the
latest v5.3-rc3) on my tegra20-tec board with the tegra_defconfig.
Unfortunately I'm getting a "Kernel panic - not syncing: Attempted to
kill the idle task!"
I'm currently out of ideas on what to look for, so any help would be
greatly appreciated.
Thanks & regards;
Richard.L
