JetPack 4.6.3 preempt-rt patkernel: reboot loop

[DaveYYY]

Hi,

thanks for reporting.

I want to make sure that the patch shared below just prevents the device from rebooting, but kernel will still gets locked in other use cases, right?

JetPack 4.6.3: dmesg hangs the kernel and the device reboots

Hi, we currently have a temporary solution: Please comment out the following line in Linux_for_Tegra/source/public/kernel/kernel-4.9/kernel/printk/printk.c error = syslog_print_all(buf, len, clear); it’s line 1492 on my side, and inside function do_syslog(), make sure to allocate it correctly if the line number is different. After the change, follow the developer guide to apply rt patches and build the kernel. https://docs.nvidia.com/jetson/archives/l4t-archived/l4t-3273/index.html#page/T…

Have you experienced other scenarios that also cause kernel to lock?
