Comment 3 for bug 1916112

I can confirm the issue (tested with Jetson Nano and Xavier running Ubuntu bionic).

Linux starts booting, shows "Welcome to Raspbian GNU/Linux 10 (buster)!" after 33 s on Nano, but QEMU crashes after showing "Mounted Kernel Debug File System" about 77 s after start.

Debugging is difficult because the failing address in code_gen_buffer changes for each new run, so setting a hardware watchpoint does not work. The disassembly is always the same, only the address of the code changes.

The same test works better when I use the TCG interpreter (./configure [...] --enable-tcg-interpreter) although a warning says that TCI has less reliability and that it is strongly recommended to remove the --enable-tcg-interpreter configuration option. It reaches "Welcome" after 205 s on Xavier, "Mounted" after 420 s and finally goes into emergency mode because of "Dependency failed for /boot". Linux shows "Press Enter to continue.", but I don't get a command line after doing so.
